version: betteranimalsplus-1.16.5-10.2.0

Seems to happen periodically in my world with no specific action taking place.

any thoughts?

Thanks for your hard work!

The upstream issue has been resolved with Mobifier 1.0.2, by the way.

Update:
The location the crash took place had a few skeletons around it in the overworld. I could not load in with betteranimalplus mod in my mod folder but when I took out the mod I could load in and tp to the location where everything ran normally. I'm thinking a mob from betteranimalplus is getting hit by a skeleton arrow and crashing

Here is a follow up log I was able to recreate the crash while a skeleton was fighting a coyote. As far as I can tell it only seems to happen to coyotes

Can you try to reproduce this without mobifier and performant?

If it still happens without those, maybe disabling the bleeding effect from Majrusz's Difficulty?

Sorry for the late reply, been a busy week.

So the culprit seems to be mobifier with betteranimalsplus (specifically the coyote, the feral wolf doesn't crash) as I can reproduce the crash with both mods on my server. The crash does not happen with makrusz in my mod folder. All this was tested while using performant.

Both your mod and mobifier are key to my modpack so ill continue to keep the coyote disabled on my map

This seems to be an issue with Mobifier. I've created the issue for you.
