I've been trying to complete all of the achievements in Elder Scrolls V: Skyrim. I've run into quite a bit of trouble with the Oblivion Walker achievement. I've recieved all 15 items necessary for the achievement, but it will not unlock. I've tried several fixes online but nothing seems to work. It seems like something is broken beyond what I can fix in game. Customer support told me that I could receive the achievement after making a post here. Please let me know what else i need to do to solve this problem.
