It might be a glitch or quest-centric like you thought. I found a glitch with a mission... you can trigger the quest again by reading a book again. I didn't actually visit the quest location a second time to see what happened, plus I had the quest item in my inventory already.

Lvl9 with 41 sneak? Impressive. You must sneak around a lot. I don't have the patience for that, so my sneak is only in the 50s and my character is lvl19. Is this your only character or did you start over?

Has anyone tried any of the Skyrim mods? http://www.pcgamer.com/2011/11/14/th...m-mods-so-far/

I've installed the enhanced night sky mod (#5) and it's awesome.
