Thrower is null crash

[WenXin20]

Issue Description:

Crash Report
The game sometimes crashes from a null "thrower".

What happens:

I'm not too sure what happened, but I had some pokecubes lying on the ground, after reopening the game, that is when it crashed. I suspect that it could be the pokecube's owner isn't being saved, which could possibly crash when a pokemob gets captured by it?

What you expected to happen:

No crashes

Steps to reproduce:

1. Throw pokecubes on the ground
2. Reload world
3. Have a pokemob collide with the cube?
