So I'm in Ered Luin starting my crafting career. I took on the quest "Intro to Prospecting" from the master of apprentices, Alfwin. Quest tracker says to speak with the supplier in the crafting area. The only supplier I see is only a few feet away and it's pretty close to the crafting area. When I right click on him, his shop items pop up and no further quest advancement. What do I do?
