what does this mean
>add crash refinedrdsml310
What should the logs match (regex)?
RefinedRDLib.*ResizeGrow
What should the response be?
Refined R&D Lib crashes with SML 3.10.0 installed. Use the mod manager to switch to SML 3.9.1 until it is fixed.
Known crash 'refinedrdsml310' added!
Thanks, Robb. You read my mind
will set a reminer to remove the fred autoresposne once they update it
how do i manually swap from 3.10.0 to 3.9.1?
Solution
Filter your mods by Dependency (top-right menu), then select SML

wonderful thankyou very much
seeing if it works rn
server doesnt crash now after switching to 3.9.1 but still unable to join server

Something is causing the replication reliable buffer of
[UActorChannel] Actor: BP_PlayerState_C /Game/FactoryGame/Map/GameLevel01/Persistent_Level.Persistent_Level:PersistentLevel.BP_PlayerState_C_2147465807
to be overburdened! The limit is 8 but there were 257 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.
