Something is causing the replication reliable buffer to be overburdened, causing you to be disconnected! This crash tends to happen when joining a multiplayer game with a lot of content, or when a mod accidentally tries to replicate (tell the client about) too much information at once. 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 removing mods that introduce lots of recipes or schematics (HUB/MAM/shop unlocks) or Mod Savegame Settings. -# Rule logic: https://regex101.com/r/MXqmd4/

Did you have it installed on both the server and the profiles of any players on the server, including you? Because if so we might need to ping the mod author if there's a bug somewhere, or track down the mod conflict if there is one

Just have to confirm so I'm not pinging the mod dev prematurely @Acxd {Alphabet Soup} just FYI, when you're feeling up to it there might be a bug with Customizable Awesome Additions on dedi Otherwise, we have a server together where Acxd might see it sooner if you wanted to post a bug report for this there >FL
