Man, this svcks. I obtained the book The Old Ways before Urag gro-Shrub assigned me the quest. Now not only will he not accept the book, I can't even drop the thing. So now I have a mission that's impossible to complete and I can't do any more Fetch Me That Book! quests.

Oh. It does svck

Unless I can get my save onto the PC and someone could use the console command to drop the book and pick it back up. I hear that fixes the glitch. I'm on Xbox. I'd do it myself if I were on PC.
