After updating, I tried to do the Silver Shroud mission and during one of the objectives, at the exact same point of talking to the person my game crashes. I hadn't even started this quest when I updated... I tried it 3 times, all of the times crashing, so I verified the game files via steam and it said it had to download 4.6GB of stuff that I was apparently missing. This is a huge problem for me since I only get 600KB/s download on a good day...
