Currently doing my artifact weapon quest chain on an old mage alt. While doing the quest “Ari’s Package” it reads “Bring Ari’s package to Archmage Khadgar” the quest pointer indicates that he’s suppoused to be inside the Mage Order Hall. But when I’m standing on top of the “?” indicator, Khadgar just isn’t there.
Check to see if hes still in the violet citadel area of dalaran with Vereesa I think. He tends to hang there until you do a quest and hopefully he’s still there.
