[1.3.55] Can't get rid of the Sandraven Holy Axe

Hey there,

I completed The Cradle of Fire's quest without returning the Sandraven Holy Axe. Problem is, nobody in the party uses two-handed weapons and I can't get rid of it because it's still marked as a quest item, although I can't go back and return it anymore, which is problematic as it's quite heavy.

Thanks for the awesome game!
