Bug description: When I take the quest I'm supposed to have a window appear and pick my artifact weapon, this on the other hand doesn't appear. After I've used .info on the quest, 5 of them completed the quest but I don't know how.
Proof: Will try to make a video on it.
You can see in this video how the quest is supposed to work: https://www.youtube.com/watch?v=2RY5aFEIfiQ

Update: After I went to the class hall and back to the NPC that gives the quest and abandon + retaking the quest, the window appeard.
