Issue description
I created a mod where it adds a new dimension, some new items, and a mob. Every time I try to spawn the mob, my game crashes instantly. It just freezes the screen, and I can't exit out unless I use task manager or alt + F4. I tried checking out another issue called Custom Mob Crashes Minecraft instantly when spawned, but that didn't have a solution. I am using MCreator version 2019.5, Minecraft version 1.12.2.
You are most likely doing something like using procedure on mob hurt and spawning a thing that hurts mob again which in turn triggers this procedure again until it crashes. It might not be directly this, but something similar, this usually causes this problem.
