I'm afraid it still isn't working. I'm able to pick up all Vargus' quests but i can't turn them in. Once the quests are accepted they're not "visible" anymore when you talk to the NPC. Can anyone confirm i'm not the only one in this situation? Or maybe there's an easy fix for this?

Is there any update on this matter? I know several people who would like to get their BiS Bracers :)
