So, I'm playing Cryostasis and having a grand old time, when suddenly the game crashes and I get a little box telling me I'm missing a texture. "Well, that's a real conundrum", says I, so I verified the Steam cache and there was indeed 1 file missing. What it also said was that it would be recovered or whatever, so I assumed my problem was over. Now I'm stuck at the door where I first crashed and no amount of file-verifying helps. What do I do now?
