It's another issue. Not realting to the one I try to fix

Ya. I'm trying to fix this issue. But seems not cover all situation
Is it appears when you died?

That's should not happen. How can you reproduce it?

reproduce with jar in this zip and find the log line before the crash
dawncraft-fixes-0.11.0.zip

Hit any mob from Iron's spells n' spellbooks or die from them. I'm not sure which of these conditions triggers this crash and if it only happens to mobs from this mod. I will do some more testing to find out.

I tried reproducing again with the jar and got this:

com.llamalad7.mixinextras.injector.wrapoperation.IncorrectArgumentCountException: Incorrect number of arguments passed to Operation::call! Expected 1 but got 0. Expected types were [java.lang.Object], actual types were [].
crash-2023-06-16_09.20.14-server.txt

I'll debug in local

can't reproduce after kill

dawncraft-fixes-0.11.0.zip

Ill try again because that was on my laptop

Im guessing the crash occurs when you attack and die at the same time?
