I have a vault of 130 dwellers, with 25 rooms. This took me several days to build up. Whenever I load my game, it allows me to play for about 1 minute and then crashes (to the desktop - the game just closes). This happens EVERY TIME that I load my game.
I am using a new Nvidia Shield (which is a gaming tablet), so there shouldn't be any issues with the device being able to run the game.
This is a HUGE problem. There are players paying money in order to advance their vault ... but when a save game crashes, and there is no way to fix the corrupted file, or restore an old save game, then your product has some serious flaws. Why spend $15 on a game that will just stop working in a few days? You are going to lose alot of players until these situations are resolved (and you add some cloud-based save feature, or a way to backup games locally).
Note about my time: it's been over 12 hours ... and most of my explorers are dying off. This is very disappointing. I feel like your company didn't give me hours of enjoyable experience (as I would expect from Bethesda), but robbed me of my time and energy.
