(I only sent part of the debug log, tell me if you need more)
Me and y friend have been playing on a modded server for a while. We installed rougelike dungeons, and ever since then my friend suddenly can't join. Technically he can, but whenever he does the server crashes. The server is fine when I'm on though. He swears he didn't do anything wrong. I looked up the error and anything I could find was of no help. Can someone please help me? Thanks.
