basicly what the title said, achieve is bugged or something did the quest twice and went to talk to campbell too guess i will have to do it all again...
edit:. after looking around for info it seems like the only way to get this achievement is doing it via green marker so you gotta do ALL the story up to that point again...
welp, i played during roll back and got my mount sking, but i did trade while the roll back, i even lost a prelegend (cheap one lucky) and no gems or gold back
