I've got the problem of the game crashing on the loading screen, after you select the Vault, it crashes right at the end just before its about to display the vault & enter the game.
I've done what debugging I can do of the app when it starts, I've come to the conclusion its simply running out of memory (Ram) on the phone.
I've got a 4S, whilst not optimised for, its supported as I can download the app and run it. I can also buy lunch boxes and herein lies the problem.
My thoughts are that Bethesda must have come up against this issue when they tested the app (yes, I'm sure they did some testing) they must have known that the older devices would never stand a chance of getting to the 200 dweller limit (I was at 50, btw). So why, if they knew that the game would crash at some point, do they allow the app to be run on those devices, take people's money, knowing that they'll run into an unsolvable problem.
Hell, this bug even affects people on new hardware that have got up towards the 200 limit.
So, I would suggest to Bethesda, either you reduce the memory footprint so that the game loads on older devices or simply block them from playing the game.
Otherwise you're ripping people off as you're selling stuff in the knowledge the game will sooner or later get to the state where it will not work.
And refunding those who request it would be a good place to start too.
At this rate, its putting me off buying Fallout 4, I thought Bethesda were better than this.
What do we have to do to get a response from Bethesda, start a class action law suit? Surely not.
