I just got back to playing for the first time in a couple months and I can't find the Thorn Quest even though I know I had it for a fact. I also have earned Rose so that proves it. I tried looking in the quest vault and then returning to the salt mines to try to find the quest again but the salt mine place is gone and the quest vault doesn't have it. What the heck am I supposed to do? I would like to get Thorn through the quest not the stupid exotic archive thing.
