Whenever you pick up a quest item, it is stuck in your inventory from then on. You can't store til you need it, or discard it if you have no interest in the quest. The worst part is, if you complete the quest and you still have the item, you are stuck with it FOREVER. Alot of the quest items don't weigh anything, so all they do is clutter up your inventory unnecesarily (which, while annoying isn't a huge deal) but some of them do have weight, and that IS a huge problem, since there is only so much your character can carry. It seems like a simple enough fix for the next patch, so please, I'm tired of carrying around all of this (now) useless stuff. Please consider fixing this.
