Had 200 dwellers including Legendaries and great weaponry and one day game decided it wanted to crash on loading screen and is unplayable. Won't even get to vault selection. Tried soft and hard reset, closing all apps, backup/restore, uninstall - nothing will fix this. New update did not fix problem. As game data is local, I had to uninstall and reinstall and lost countless hours of investment. This problem apparently has affected others and no one has responded to these issues of crashing. We need a fix, please. Unfortunately my progress is lost forever, hoping this gets fixed for others soon.
