I've recently finished going through an area where I found a ruby dragon claw and a book about King Olaf. Both of these items are quest related, but once I completed the quest (miscellaneous quest about hidden power in from an anonymous note), both the book and the dragon claw are still quest items and I cannot remove them from my inventory, even though I completed the quest.
Has anybody encountered this before? If so, can these items be removed from my inventory, or will I be stuck with them like in Oblivion where I have 30 quest items cluttering my inventory?
