I'm on an Iphone 6s, and I hesitate as the last time I updated, I had to create a new vault because it would freeze every time I tried to load the Vault which pre-dated the update.

I like the idea of pets etc... and mass selling junk from the wasteland.. But I lost my entire vault last time around because I wanted to update in order to get Mr Handy's..

I am at 200 dwellers, all WELL equipped, with MR Handy on every floor, and I'm just working to max all of the stats out on the last 80 or so dwellers who arent quite max, and are not yet lvl 50... getting there.

If anyone has any tips, or any advice as to whether or not I can safely update, please do let me know...

Cheers,
