Description

This crash appeared after a server restart, and became stuck in a crash loop until we disabled the mod. Never seen this before. We did update forge to 43.3.8, unsure if that's related. However we updated the forge version a few days before these crashes started.

Steps to reproduce

I have NO clue. This appeared after a server restart, and the server is not startable with the flan mod anymore.

Logs

debug (35).log

I found the issue! When the server restarted, it saved a copy of a player's UUID for some reason and it bugged out! If anyone experiences this issue, go to playerdata > claimData > look for a UUID that has "copy" in it and remove it.
