Updating from 4.8 preview 2 to 4.8 caused packaged game not to start

Alright guys, after creating a circle of energy drink around my PC and sacrificing a pizza to the code gods. I found that the game instance i had created in preview 2 was in fact a heretical troublesome area. Needless to say, after smiting it with my mighty delete button, i was able to play my game just fine. So moral of the story is, any problem can be solved with enough caffeine.
