Alright. I have this detail log. It seems that there's an unknown item entity luring through my world...

Story:

So I was making a entity 303 custom head from dragnoz's custom head generator. I gave it no name.

I put the finished command in the command block. When the head was given, I crashed. The ID of the entity: 4243
