Same here on my iPad Air.
It randomly crashed and when I tried to restart, it lets me pick the vault but crashes about 30 seconds after starting the loading animation.
I had 33 dwellers. I've tried restarting, etc. Nada.
Very sad right now. My dwellers need me.
Edit: I just read that bought lunchboxes stick with the vault you bought them under. So either I need a way to fix this or I want a refund! Grrr
I have the exact same issue as http://www.gamesas.com/user/951322-kanyehobbitkind/ with my Ipad mini. And every time I try getting back in, it says the previous vault I created isn't there. So each time, I'm creating a new vault.
Same prob here. crash after opening.
please advise if anyone finds a fix.
I have an iphone 6 and I'm still having this issue. Since this morning I see the loading screen and then it crashes to my homescreen.
