Troubleshooting

Always check the MelonLoader log first: …/Schedule I/MelonLoader/Logs/ (newest file). Side Hustle logs when it initializes, every gamemode that registers, and any problem with a warning.

The “Side Hustle” entry is missing from the main menu

• Mod not loaded? The log should show Side Hustle <version> ready - N gamemode(s) registered so far. If not, SideHustle.dll is not in …/Schedule I/Mods/, or MelonLoader/S1API are not installed.
• Hidden by the toggle. Check Enabled in UserData/MelonPreferences.cfg under [SideHustle_01_Main]. Return to the main menu after changing it.
• Menu not laid out yet. The button is injected when the menu scene loads (with a short retry). Backing out to the main menu again re-injects it.

My gamemode does not appear in the list

• Registered too late or not at all? The log should show Gamemode registered: '<Name>' (<id>). Register in your OnInitializeMelon - see API Reference.
• Side Hustle absent at load. Add [assembly: MelonOptionalDependencies("SideHustle")] so the hub loads first, and make sure SideHustle.dll is installed.
• Duplicate id. Registering reuses the row for an existing Id; give each gamemode a unique Id.

Selecting my gamemode does nothing

• Your launch callback is null or throws - OnLaunchSingleplayer for Singleplayer / Hybrid, or OnHostMultiplayer / OnJoinMultiplayer for a Multiplayer gamemode. Check the log for an exception from your callback.
• A Multiplayer-only gamemode shows a Host / Join choice instead of launching directly; pick Host or Join.

The menu does not come back after my gamemode

Call ctx.ReturnToHub() from your gamemode when it finishes (e.g. on a Back button). If your overlay covered the menu, make sure you also tear it down. OnExitToHub is invoked when Side Hustle initiates the teardown.

A non-friend can’t join my public lobby (they drop after a few seconds)

Schedule I itself kicks any joining player who is not on the host’s Steam friends list - the connection establishes, world data even starts loading, then the host drops them about ten seconds in (the host log shows Player <name> is not friends with the host. Kicking from game.). Side Hustle lifts that kick while you host a Side Hustle gamemode, so anyone can join your public or password-protected lobbies.

• Make sure the host is on Side Hustle 1.5.1 or newer. The fix runs on the host, so only the host needs the up-to-date build - a joiner can be on any version. When hosting, the log shows [mp] public-lobby access installed (non-friends may join a hosted lobby).
• It only applies to Side Hustle-hosted sessions. Normal co-op started outside Side Hustle keeps the vanilla friends-only behaviour.

The join times out at “LoadingData” / “join did not complete”

• Different builds. Everyone in a session should run the same version of the gamemode. Side Hustle warns on the browser card and in the log when your build differs from the host’s - update to match.
• Different mod sets. If the host runs mods that add networked objects the joiner doesn’t have, the world sync can stall. Host with “Required mods only” (if the gamemode declares a mod policy) so both sides run the same curated set.
