Have you tried playing the game with WiFi turned off on your device?
I was having the same crashing problems.
After my 5th reinstall, I turned off WiFi, and so far the game is still running smoothly after 110+ Dwellers.
If you get a chance to do a clean install.
Start over with no WiFi connection.. see how far you get.
Also what device your are using and what iOS version?
This app is F.U.B.A.R.
To anyone experiencing the game breaking bugs, request a refund and avoid this game. Let them bring out a decent fix or update first, maybe then I'll reconsider it. But for now, even if they ever pathc it, I'm not that eager to test my luck as the developers don;t even recognise any issue at all.
I would sincerely be shocked and awed if they actually did....
Will the wifi thing help with the slowdowns with 100+ dwellers? It is impossible to scroll through all the dwellers, without it crashing out of the dweller screen.
No. Disabling the wifi is not a remedy. With all respect to the person who came up with this as possible solution/workaround, it is just wishful thinking. There is no magical option to turn off or on to fix your game.
Bethesda not responding to these bugs is just appalling. What are we to expect from this company, anymore? Previous games were bug ridden. This is no exception...
