[REALMS-1135] Exception in Thread and Process Monitor Errors

I'm getting an "exception in thread" error that also results in an expected character error. This happens when I attempt to upload the world to my Realm. It's not crashing. It just sticks on "preparing world". I can press cancel and back out just fine. This error doesn't seem intentional, so I'm posting it here.
