In the needle and bone quest, i crafted the 2 duskwind tunics, (I threw one away if that is necessary information) and Balthazar will not take my quest back, here are some screenshots if they help
It wont let me post the screenshots, sorry, but i would really like some help with this
You solved your own problem... you threw one away. You must have ALL items required in your backpack to get credit. You will have to craft another duskwind tunic to turn this quest in. You don't need support or screenshots, you just have to redo it.
