| Problem | Likely Fix | |--------|-------------| | Can’t see Multiplayer button | BepInEx not installed correctly; check game log in BepInEx/LogOutput.log | | Connection timeout | Firewall blocking port 7777; host must allow inbound rule | | Desync (settlers in wrong places) | All players rejoin; if persists, host saves and reloads game | | Version mismatch | Ensure all players have identical game version + mod version | | Mod crashes on load | Remove other mods; test multiplayer mod alone first |
