Polyfill changelog

All notable changes to this project are documented here.

[0.9.26] - 2026-08-26

Fixed

Absorbent Soil and NACops are no longer listed as broken. Both work on this version - the report was wrong about them, not the mods.

[0.9.25] - 2026-08-26

Fixed

Your Over The Counter manager stops turning into a townsperson - their face, their name, their stock. If a manager is missing after you load a save, rejoin and they come back.

[0.9.24] - 2026-08-26

Fixed

The Tweakables app opens on your phone again instead of sitting there dead.
Suppliers show you their stock at the meetup. They used to just greet you until you shoved them.
GraphicsMOD’s lighting option turns the sun off again.

[0.9.23] - 2026-08-21

Fixed

A patch a mod cannot bind no longer blocks every later patch of that same method. Harmony keeps the failed entry, and 0.9.19 left it there.
Tweakables can raise how often a customer orders again, and GraphicsMOD’s lighting option switches the sun instead of doing nothing.

[0.9.22] - 2026-08-21

Fixed

Deal Optimizer re-evaluates a counteroffer after you change the quantity. The method kept its name and swapped its argument type, which Harmony can neither choose nor bind.
Tweakables can patch the handover price box and the blackjack bet slider again. Polyfill’s stand-ins carried the new argument names, and a patch binds by name.

Added

The blackjack bet slider, its handler and the bet label are reachable on the screen again, after 0.4.6 moved them into the panel every casino game shares.

[0.9.21] - 2026-08-21

Fixed

Enhanced PD stops logging an error every second. 0.4.6 moved the player lookups off Player onto PlayerManager, and the mod asks the old address once per raid tick.

[0.9.20] - 2026-08-19

Fixed

The GreenTab app comes back after a trip to the main menu instead of failing to register, which took the whole app down rather than its icon.
Unicorn’s Custom Seeds can put its seeds in a supplier’s shop again. Reading the list was bridged and writing it back was not.
Installing through Vortex puts the plugin in the game’s Plugins folder instead of bepinex/plugins.

[0.9.19] - 2026-08-18

Fixed

The Heisenberg mod delivers Heisenberg again instead of a standard chemist: the flag that says an NPC has a last name moved in 0.4.6 and nothing had put it back.
Deal Optimizer works on counteroffers and street deals again, and no longer throws at startup.
One patch a mod cannot bind no longer costs it every patch after that one - Deal Optimizer lost seven working ones to a single dead target.

Added

A method that kept its name and now hands back a renamed type is repaired instead of only listed.
The report names a patched method the game split into two overloads, which Harmony refuses to choose between.

[0.9.18] - 2026-08-17

Fixed

Despawning an NPC stops filling your log with errors. The game asks one list of schedule actions whether they should start without checking they still exist.

[0.9.17] - 2026-08-17

Fixed

The Over The Counter manager panel goes away when you put the clipboard on another employee, instead of staying up and drawing over theirs.

[0.9.16] - 2026-08-17

Fixed

Instant Pack works again. The packaging and mixing screens renamed the property that hands out the station they belong to, and mods that ask for the old name got nothing.

[0.9.15] - 2026-08-16

Changed

The log names which character each Over The Counter customer was built from, for the first eight. Ask for it if your customers all look alike.

[0.9.14] - 2026-08-16

Fixed

Suppliers open their sales page again and the GreenTab app takes input after you return from the main menu. Both died in the same call Polyfill had written wrong.

[0.9.13] - 2026-08-16

Fixed

Over The Counter’s manager panel goes away when you put the clipboard down, instead of staying up and overlapping the next employee’s panel.

[0.9.12] - 2026-08-15

Fixed

You can move again after putting the manager clipboard away. It was hidden without being taken off the input stack, so the game still had it open while the screen said otherwise.

[0.9.11] - 2026-08-15

Fixed

Ultimate Mod Menu starts. Its third way of looking a type up killed the game too, and so did the way Polyfill answered the first two.

[0.9.10] - 2026-08-15

Fixed

Ultimate Mod Menu gets past its clipboard setup. 0.9.8 covered one of its two type searches, so the crash moved from the police patches to the next feature instead of going away.

[0.9.9] - 2026-08-15

Fixed

Over The Counter can dress a drifter again. It writes a field 0.4.6 deleted, and the whole routine stopped before its own error handling could run.

[0.9.8] - 2026-08-15

Fixed

Over The Counter’s customers stop all being the same person. They were cloned from one prefab; now every spawnable civilian gets a turn, and the log names which ones your game has.
Giving an Over The Counter manager a route works again. The button did nothing because the panel named a UI class 0.4.6 removed, which stopped the whole method from running.
Ultimate Mod Menu no longer kills the game on startup with no message. It searched for game types in a way that loads every type there is, which the game does not survive.

Changed

polyfillprobe now calls static members too, so a repair like Singleton<T>.Instance can be checked rather than only listed.

[0.9.7] - 2026-08-15

Fixed

More Foot Patrols staffs its routes again. It cloned a police prefab this build no longer has; the officers now come out of the police station, two held back for callouts.

[0.9.6] - 2026-08-14

Fixed

Deal Optimizer reads and sets the handover price again, and asks a dealer how much of a product it has. All three kept their meaning and lost their names.
Always Show Distances On Compass finds what a compass marker points at. 0.4.6f5 renamed it to TargetTransform.

[0.9.5] - 2026-08-14

Changed

Schedule I 0.4.6f13 is a build these repairs have been read against, so they stop reporting themselves as unchecked on it. Nothing 0.4.6f13 changed is anything they touch.

[0.9.4] - 2026-08-14

Fixed

The manager clipboard in Over The Counter answers the interact key again. It was listening on the key 0.4.6 moved its button to, so the prompt appeared and nothing happened.
NPCs stop going unresponsive after you trade with them. The storage window lost the event a mod uses to put them back, so its cleanup never ran.

[0.9.3] - 2026-08-14

Fixed

Custom Commands Framework stops killing the game on startup. It reads every type in every loaded assembly, and doing that to the game’s generated ones ends the process with no error at all.

[0.9.2] - 2026-08-14

Fixed

Over The Counter’s hired manager stops throwing every tick, which is what froze the clipboard when you tried to give one a locker. It was being built out of a cleaner, same as the drifters were.

[0.9.1] - 2026-08-14

Fixed

Trees stop growing every time you reload. With Bigger Trees installed, each load multiplied the size again instead of setting it, so dying and loading gave 2x, then 4x, then 8x.

Added

HelpHarmonyFind in MelonPreferences switches off the one layer that sits in front of another mod’s code, for ruling it out when something misbehaves. The repairs themselves stay.

[0.9.0] - 2026-08-14

Fixed

Mods stop throwing thousands of errors a session. A type Polyfill put back had its own members skipped, so one ATM reading alone threw once a frame for as long as the game ran.
OG Backpack saves and loads its contents again, and its station panels work. One dead patch target was taking the whole class with it, five times over.
Lithium’s shop prices refresh again. 0.4.6 renamed an argument, and Harmony matches those by name.
Lithium’s drying rack and ATM screens work again.
A nested type Polyfill put back is nested again. It was written at the top level under a name nothing asks for, so the repair reported success and the mod threw on the type.

Added

polyfillfixes gains split-screen-patches: where 0.4.6 split a station screen’s SetIsOpen into Open and Close, a patch aimed at the old name runs again from both.
The report says when a patch will be moved rather than left dead, so a working mod stops being listed as broken.

[0.8.1] - 2026-08-14

Fixed

Hiring a manager in Over The Counter works again. It sets the NPC’s pickpocket target, which 0.4.6 kept under the name its private field carries now.
More Foot Patrols spawns its officers again. ApplyShapeKeys lost a flag, and what the flag switched off is what 0.4.6 does either way.

[0.8.0] - 2026-08-14

Fixed

OG Backpack opens with B again. The storage window has three Open methods, all three grew an argument in 0.4.6, and the repair answered for the wrong one.
Mods that patch the mixing or chemistry station screen work again. Those two and two more were renamed in 0.4.6, and a patch aimed at the old name now reaches the method the game calls.
StackPro talks to other players again. 0.4.6 took the Steam ids off the lobby, and all three are still derivable from what it kept.
Lithium reads a dealer’s type and an NPC’s walking speed again, and its ATM screen patches apply.
DealOptimizer finds the counteroffer price box again. It became an AmountSelector, and the input field inside it is the same control.

Changed

The report stops naming members that were never gone. 0.4.6 moved eight of them onto base classes, where the game finds them anyway; four mods in one report were called blocked over that alone.
One repair that fails no longer costs the other fifty. An emitter that threw took the whole assembly with it, and the log said only that it had been left alone.

Added

When a member moved to a base class under a new name, the report says which class and which name, so a mod author has an answer rather than a dead end.
polyfillfixes gains patches-on-grown-overloads, which moves a mod’s patch onto the method the game calls when the old signature only exists because Polyfill put it back.

[0.7.4] - 2026-08-14

Fixed

Another fix for the management clipboard: the stand-in for the deleted NPC selector screen was missing the one property the mod reads off it.

[0.7.3] - 2026-08-14

Added

polyfillprefab tree <name> walks a UI object in debug builds, for mods that find their way by a spelled-out path and break when a screen is redesigned.

[0.7.2] - 2026-08-13

Fixed

Another fix for Bella’s handover screen: it reads the customer’s favourite drug with no count check, and hers has none.

[0.7.1] - 2026-08-13

Fixed

Bella’s handover screen shows your options again. It reads the customer’s preferences straight out, and OverTheCounter’s own customer has none, so the screen never filled in.

[0.7.0] - 2026-08-13

Fixed

OverTheCounter keeps its manager panel AND the game keeps its clipboard. 0.4.6 deleted the NPC selector screen, which killed both; it now answers that it is not open, which is true.

[0.6.2] - 2026-08-13

Fixed

OverTheCounter’s route picker closes again without choosing. Right-click, which is what the mod’s own community repatch picked after 0.4.6 removed the Escape and Back buttons.

[0.6.1] - 2026-08-13

Fixed

The management clipboard works again with OverTheCounter installed. Its patch asks for a screen 0.4.6 removed, which killed the whole clipboard and filled the console every frame.

[0.6.0] - 2026-08-13

Fixed

T.H.M’s syringe and garrote kill again. They were repaired as far as the killing blow, which then never landed and said nothing.
A type the game moved to another assembly AND renamed is put back properly. The old repair crashed any mod method that mentioned it, past that mod’s own error handling.
Mods built before 0.4.6 press the key they mean to press. The game deleted 14 entries from the middle of its button list, so Interact became the vehicle-lights key.

Added

polyfillprefab thm and polyfillprefab doors report why a mod’s action did nothing, in debug builds.

[0.5.2] - 2026-08-13

Fixed

Doors a mod puts up in a property you already own can be opened again. They locked themselves and waited for a purchase that had already happened, showing no prompt at all.
Counters, switches and doors a mod spawns come out visible. Half the copies Polyfill could hand over are switched off, because the game deactivates a building’s interior while you are away from it.

Added

Bigger Trees makes the trees bigger again. The game stopped drawing terrain trees in 0.4.6f5 and the mod’s setting reached nothing. TreeScale in MelonPreferences sets the size, 1 leaves them alone.

[0.5.1] - 2026-08-13

Added

OverTheCounter’s drifters stop throwing an error every tick. The mod asks for a character the game no longer has and fell back to an employee, which crashes without a workplace.

[0.5.0] - 2026-08-12

Fixed

After a Schedule I update Polyfill starts from the game’s new files. It used to keep writing its copy of the old ones back over them, which broke mods that had been fine.
Repairs keep working when the game reaches 0.5.0 or 1.0. Version numbers were compared in a way that read 0.5.0 as older than 0.4.6f5, which would have switched the rename history off.
A repair a person wrote by hand is used before one guessed from spelling. Two similar-looking names could stop the better answer from being used at all.

Added

The report says what Polyfill DID, not only what it found. polyfillexport gains a REFUSED section for every repair it had a candidate for and did not trust.
polyfillregen has MelonLoader build the game’s generated files again, for when Polyfill reports that it has no untouched copy of one left.

[0.4.3] - 2026-08-12

Fixed

OverTheCounter’s co-op sync is no longer switched off by a version number. It demanded exactly the SteamNetworkLib it was built with, and the newer one carries everything it calls.

[0.4.2] - 2026-08-12

Fixed

The supplier’s meeting greeting and its reply work again. 0.4.6 stopped keeping either in a field, and a mod reaching for them was throwing six times a minute.

[0.4.1] - 2026-08-12

Fixed

Trees no longer stand inside the buildings a mod places. 0.4.6 draws them from a baked texture rather than from the terrain, so clearing the terrain had only been taking their collision away.

[0.4.0] - 2026-08-12

Added

Renames the game made in any build since 0.4.4 are followed on their own. Polyfill carries the game’s own history, chained over 14 versions, and asks it when the installed game cannot answer.
That includes a FishNet RPC whose hash moved with its signature, which nothing on the installed game can work out by looking.

[0.3.0] - 2026-08-12

Added

Per-mod fixes: one small module per mod, for breakage that has no name in the metadata to repair. polyfillfixes lists them and switches one off.
Mods built on S1MAPI get their doors, switches and counters back. 0.4.6 stopped listing those as network-spawnable and the lookup only ever searched that list, so they came out empty.
- The game keeps no loose copy of those, so what gets cloned is one already standing in the world. It looks right and may behave like the one it came from. polyfillfixes off s1mapi-prefab-lookup.
The same mods also follow prefabs the game renamed, such as the _Built suffix 0.4.6 put on placeable furniture.

[0.2.0] - 2026-08-12

Added

Mods that build their own NPC run again: 0.4.6 moved the NPC’s name, ID, mugshot and inventory settings, and writing them killed the mod.
More names get matched. A member renamed from CustomerSlots to _customerSlots is found now, which brings back the weather reading and the handover screen for older mods.
Two more kinds of break are repaired: a type that only changed namespace, and a method that grew an argument. That is OverTheCounter’s contacts app and its storage screen.
T.H.M - The Hitman Mod now has a repair for all 6 things it asks for, OverTheCounter Dispensary for 29 of 40. It was 5 and 4.
polyfillprefab <name> says whether the game still has a prefab a mod spawns by name, and what is spelled close to it. Renamed prefabs used to fail in the Unity log where nobody looks.

Fixed

Boots that died with no message. A mod asking Harmony for a type by name made the game load every type in every assembly, and one of them takes the process down.

[0.1.3] - 2026-08-11

Fixed

The store pages said your files are never touched and then offered a command to undo things, which made no sense. It patches the game, not your mods, and now the text says so.

[0.1.2] - 2026-08-11

Changed

The store pages are shorter and say what the mod does in one line. The previous text still read like documentation instead of a mod page.

[0.1.1] - 2026-08-11

Changed

The store pages now say what the mod does in plain words. The old text explained the mechanism instead of the problem, so nobody could tell whether it was for them.

[0.1.0] - 2026-08-11

Added

Mods built for an older Schedule I keep working: the names an update took away are put back into the game’s generated interop assemblies, pointing at wherever the thing lives now.
Your mod files are never touched. Repairs go into MelonLoader’s own generated assemblies, and the untouched copy stays beside them as <name>.dll.polyfill-orig.
polyfill in the console says what every installed mod is missing and what it was matched to, and polyfillexport writes all of it to one file you can send on, with no paths in it.
polyfillrestore undoes every repair on the next launch. It cannot happen sooner, because the assemblies are in use while the game runs.
DryRun works out what is missing and changes nothing, so you can see what it would do first.
