Hello,

Im playing with the MC Eternal Modpack. After noticing some lag spikes I started up Mission control and saw a lot of Exceptions thrown by the Hats mod:

The Version is 1.12.2-7.1.0

I hope this will help you.

Closing all issues as Hats has been rewritten from the ground up and the old mod for a long time now was no longer supported.. I'm sorry I wasn't able to address your issue. If you're still playing modded Minecraft, consider checking out Hats for 1.16.5+.
