Hello! In multiplayer the server crashes when a specific player joins, we had fixed the issue by generating a new world, however the issue is now caused by another player.

Here is the crash log from the server.

Hi there,
This is a strange one; hard to diagnose a java.lang.Error. I'm not sure that I can reliably reproduce this issue, so I can't say I'm very confident that I'll be able to resolve this one, especially considering all the possible mod interactions.

If this happens again, I suggest trying to delete the specific player's data file before deleting the world (if you haven't already tried that).
Thanks.

Ah, It appears to be a weird interaction from playerex with Eldritch Mobs mod, mostly caused by the Eldritch mobs mod itself. I have found this out on the modpack's discord. Thank you for the prompt reply though!
