Minecraft crashes in-game multiple times and all of the crash reports are the same as the one above, varying in time and location only. I believe it is not caused by a single block/creature but all that can produce this "projectile".

There seems to be a problem with the entity projectile curse. I' m not sure if the problem is that i'm using the Crazy Craft 4.0 modpack and this is an unexpected malfunction in the combination of mods. I'll be happy if there is a way to remove the entity from the game/ stop it from spawning/ to prevent the crashes from happening.

I believe I have the same error in Crazy Craft 4.0 on a server, and its causing it to get stuck in a crash-loop. It's a java.lang.UnsupportedOperationException, right?
