Hi, I noticed that occasionally (not all the time, but often enough that it becomes an annoyance), whenever I try to start up my Minecraft 1.16.5 server (Forge 36.1.24), having the latest version of Omni (version 1.2.2) loaded will sometimes cause it to crash.

Server-Side Crash Report: crash-2021-06-03_18.01.18-fml.txt

In the above crash report, part of the crash is caused separately by the Earth Mobs Mod (don't worry about this, I've already talked to the creator of this mod to fix it). However, the other part of the crash that is caused by Omni can happen regardless of whether other mods are loaded or not. I'm not entirely sure what part of Omni's code is triggering the crash, but hopefully the stacktrace error thread can help you there.
