I don't know why, but I can't enter Kolskegrr mine, the loading screen never disappears and I'm forced to restart the game.
I'm in the middle of scroll scouting, haven't gotten either Dragon or Blood scrolls, Serana is my follower and Shadowmere is accompanying me. I have a few quest items in my inventory, haven't cleared most Markarth quests, recently I finished Namira's quest, I'm in the middle of Molag Bal's quest. Have already cleared Kolskegrr mine once and have attempted receiving the quest again as a means to gain entrace, didn't work.
If someone knows why this is happening and/or how to fix this, please say so.
