Just tried that and I think you may be correct however it doesn't appear to be completing the quest for me. Not sure if it could be because I'm level 21 and it's a level 10 quest perhaps? Or maybe I need to deconstruct an item under level 10... Will post an update if I figure it out.
Edit: Confirmed. Deconstruct an item under level 10 to complete it. Thanks Methos!
Nothing happened
