When I first load the game, it works fine. As long as I keep the app running in the background, it'll work fine. Once I close it out though, next time I try to play, it won't load any of my vaults. I can try over and over, but nothing loads. So, I restart my Note4, and it works fine, again.

Nice to have this solution, but kind of annoying, and I assume, not working as intended.
