Ok, so I'm in Winterhold and I purchase the coral dragon claw from Birna's Oddments shop. I leave the shop and then realize there's no map marker or quest description. All I have is the coral dragon claw in my inventory. So I google the quest location and find out it's Yngol Barrow. So after hunting for the location for half an hour, I finally find it. My babe Lydia and I go in, and see a sudden flash of brilliant color and then everything goes black. I can still here sounds and see the HUD, but everything else is black. I can move, but cannot see where I'm going. Got out completely 3 different times and got back in, with exact same results. Couple this with random dead dragons falling from the sky and I'd say apocalypse has come to Skyrim!! WTF??!! This is embarrassing!! 43 hours in, level 21, 7792kb save file.
