having a crash using all your mods + lots more. making a custom modpack with some extra progressions. so indeed this may be a mod conflict.

but i gotta start somewhere. so heres the crash.

https://pastebin.ubuntu.com/p/kdHGc7cSr9/

my modpack contains 302 mods atm. so any details you may be able to help me resolve the issue be great.
also have a spark report showing entity AI being very high load on server
net.minecraft.world.entity.Mob.aiStep()33.18%
https://spark.lucko.me/gRSsWAvf0i

strange that the ai is mentioned in the crash. only reason i mentioned the spark report here. otherwise id have no clue where the ai is being called from. haha

any additinal tests you need me to do try and do , ill gladly do it. im developing this modpack for curseforge. heres the link

Your entity AI load has nothing to do with my mods. However, the crash will be fixed :)

Awesome thanks for the ai tip. I have a few suspects ;) keep up the great work!!

Also getting this crash during electrodynamics.common.event.PlayerHandler.compareArmor.
