How do I enable the Oculus Rift in a Packaged Game?

Looks like it’s something happening in our custom game mode. The only reference I can find to full screen is the one I put in the event graph of the game mode. There are no other references to it. But it’s still inconsistent. When you go into a level, it works, but when you exit to the main level, it is disabled. I’ll record another video.
