Crashing when making Kill Entity quests with FTB Quests.

[MangoMonke]

The game crashes when trying to use FTB Quests. When attempting to make any quest with the Kill Entity requirement, the game crashes immediately.

This happens even on a fresh install, and works fine when uninstalling/disabling Bygone.
Crash Report and log attached below.
Version is NeoForge 1.21.1

The entity in question was a Copperbug, correct? I just wanted to confirm that before proceeding further with investigating, since that's what the log seems to indicate.

No, just clicking the quest at all crashes the game instantly. I assume it is due to the Copperbug causing issues, but just trying to make ANY Kill Entity quest immediately crashes the game

Oh, that's very strange. Now I'm curious why it does that! I'll try to remember to look into this when I have free time next. Thanks for the log files, by the way; those are always helpful!
