I play with last patch installed, and with all dlc. Delete my old platinum character, delete the gamedata and reinstalled all the skyrim stuff. For becoming thane of Winterhold the yarl sent me to Yngol Burrow to retrieve some kind of old helm. I went there and just entered in the burrow the game change in all dark, i can move, but i can't see anything, restore game was not allowed, savegame yes. Ok no problem, think, exit game and restore old savegame and come back. Same thing happen, so i began to worry. I try create a new savegame in the dungeon, exit the game, and restore, and it worked. Hope it helps, friends

Did you have a follower? Yngol Barrow usually goes dark if you have a follower with you.

Yes, never read anything about entering with a follower, but yes, serana was with me. I didn't met yngol's shadow, same bug? Lucky i found the helm before the final gate that remain close Any other dungeon with the same bug?
