This is otherwise a fantastic game, it shouldn't be spoiled by such basic, game breaking glitches.
Dead Space 2 was also an amazing game, but even that had one glitch too many. I can't play Dead Space 2 now without at least ONE of my suits vanishing from both the safe and store, I'm now missing my Elite Advanced Suit have no way of getting it back, as far as I know. A simple patch would have fixed this, but it was just left alone.
Don't let Dead Space 3 go the same way. It's bad enough that you slap on micro-transactions and release day DLC to bleed money out of us for content that should have been included in the game, the very least you can do is make sure what is in the game, works as it's supposed to.
