Using NULL as UUID for the drone's GameProfile is a HORRIBLE idea.

Here is the result: http://pastebin.com/raw/khEAJzjx

Please use a common fallback value if there is no UUID saved (of if the player is offline).

Also, you don't use forge's common FakePlayer class, which you should for various reasons (Then this wouldn't be that big of an issue.)

Wish this would ever be addressed.

The mod isn't being worked on anymore.

That's what wishing is for. It's okay, I managed to use the src to "fix" the null issue, but I'm not skilled enough to make it use forges fakeplayer class. Guess if I could find some forge documentation...
