Exit not crash...

So I have an issue where the game simply exits, no error, no "program has ended" nothing. I'm running it in debug mode for sure. I looked through the code and I have only a single place where there is an END command to exit the program. I commented this out and it still happens. I'm using BlitzPlay, and it seems to only happen when BlitzPlay is in use, however I looked through the BP library and there is no END command in there, or any place that would shut down the app.

I have no idea how this can be happening, has anyone seen anything like this or know of a function that can simply exit the program for no reason without calling an error or some kind of dialogue box?

Thanks guys.
