Something is causing the replication reliable buffer of
[UActorChannel] Actor: FGConveyorChainSubsystem /Game/FactoryGame/Map/GameLevel01/Persistent_Level.Persistent_Level:PersistentLevel.ConveyorChainSubsystem
to be overburdened! The limit is 8 but there were 274 items.
This crash tends to happen when joining a multiplayer game with a lot of content. It can sometimes take a while, ex. a certain number of buildings placed or schematics to be unlocked, for the problem to actually appear. Try the following:
- Installing the "Fix Reliable Buffer Overflow" mod created by the SML team to mitigate one of the most common causes of this crash
- Removing mods that introduce lots of recipes or schematics (HUB/MAM/shop unlocks) or Mod Savegame Settings.
