Issue Description:

After throwing a repeatcube at a wild pokemob, the game crashes to desktop while the repeatcube is in midair just before hitting the target.

This occurs both with species I haven't captured before, and species I have. Occurred 5 times out of 5 that I tested it.

After restarting minecraft and loading my world again, the pokemob is in the cube, and gives the usual message that it was caught successfully, after which it acts like a normal pokemob.
