Ticking Entity Crashes

[InterPlay02]

Hi!

I have two chrases because of ticking entity when I was on the moon. And the first entity was the Wither Witch. I don't know why this happens, but then I disable the witches to spawn on the moon. But then, the Concussion Creeper was the second one. I don't even know if this was the real cause of the crash.

Here is the two log files:
for the Wither Witch:
