I am at a loss as to how to finish the “Engineers and Archaeologists” quest line. According to BtWQuests there may be a quest called “Keg Run” that I need to completed but I’ve already completed the other quests before and after it so Mountaineer Rharen won’t give it to me. Is there any way to work around this? I have 3 more areas to go for the Loremaster of the Eastern Kingdoms achievement and this is driving me insane.
