About Fix Reliable Buffer Overflow
From ficsit.appFixes the Reliable Buffer Overflow caused by the conveyor belt chain subsystem when there are too many items
Satisfactory 1.1 has changed how conveyor chain replication works, making this mod no longer relevant. If you're trying to fix the "Outgoing Reliable Buffer Overflow" crash you will have to try something else.
Old content (for historical purposes):
When too many items are added by mods (~1000 items total), in multiplayer, the game will kick the player with an "Outgoing Reliable Buffer Overflow" error. This happens because the conveyor chain subsystem will try to send all the item types to the client when connecting, causing too much data to be sent at once. This mod fixes this issue by splitting the item type list into smaller chunks.
Sending these chunks happens outside the regular client join flow, so it is possible that the items on conveyor belts take a bit longer to appear on belts for clients immediately after they join.
While this could have been built into SML, we hope to allow vanilla clients to join an SML server in the future. This fix would prevent that from happening, as installing it on only one side prevents items on conveyor belts from ever loading for the client.
