In the quest where Urag (I think that's the Orc librarian at the College's name) asks you to get a copy of War of the First Council from a Dwarven ruin, I've encountered a glitch. I explored said ruin and got the book before he gave me the quest, and now the game won't recognize that I have it. The quest marker directs me to the chest in the ruin where I found it, but of course I can't pick it up since it's now in my inventory and I can't drop it and re-get it since it's a quest item.
