Game Freezes When I Attack a Creeper.

Put the summary of the bug you're having here

What I expected to happen was The creeper would just blow up and die.

What actually happened was the creeper was at the point where it was expanded about to blow up and my game froze.

1. Go up to a Creeper
2. wait until it gets to the expanded creeper so its about to blow up.
3. game freezes
