I can neither complete Ascendant Alloy Requisition quest, nor delete it. I don't own the Witch Queen expansion, so, I think, I wasn't supposed to have this quest, but I found it in my quest archive after WQ was made free for a few days before Lightfall launch. Currently it is in my quests tab, and I would like to be able to just delete it, but it has no respective button to do so. Is there anything I can do to fix this except buying the WQ?
