Great and fun game, but like clock work I play for a while
then it consistently crashes.
It's almost like it's time play based or progress based.
I've deleted and restarted at least ten (10) times.
My personal experience is never more then 25 dwellers and never past weight room.
I'm playing on am I phone 5 with 5 GB free space, not that that matters since EVERYONE is crashing no matter what they are running.
