Anyone experience this? I have a stack of 6 Giant's Toes that I can't sample, sell, drop, remove, or use in alchemy. I just recently picked up a glass 1h sword called Grimsever that can't be sold, dropped, disenchanted or removed either. When trying to remove these items a message appears that says something to the effect of "Can't remove Quest Items." So any giants toes I pick up are dead weight and the sword is a permanent 14 pounds i'll never be rid of.

I think the Giant's Toe glitched a ways back when I picked one up off the floor in a quest. And the sword I picked up off a table in a dungeon.

I've got 4 Unusual Gems that gives me the same message. My problem is I have a quest to locate someone who may know something about these gems. When I go to this guy he tells me to leave him alone and you don't even get the option of interacting with him.
