I have been on a quest to return The Old Ways book. I have the book, the librarian doesn't have the pop up to give it to him. I found the book on another quest in the place where it is located. I picked it up before the quest and cant give it to the librarian at the College. I've been back several times to the finding sight and the College. I have both the Hearthfire and Dawnguard add ons.
