I bought the Skyrim expansion Dawnguard right after it was released, and got the first achievement "Awakening" pretty fast.
I got all other achievements in the game and have gotten all in Dawnguard aswell, but on the overview it says I only have 59/60 Achievements. If I look on my stats here on xbox.com, it also says I haven't gotten it, the same as on my xbox, when I look at the overview. However when I go into the achievement list for Skyrim on my Xbox it says I have 60/60 Achievements unlocked, including "Awakening". I tried doing the quest Awakening again, but it still didn't correct it self.
I know it's not a huge problem by any means, but it's a little annoying anyway. So I was wondering if there is something I can do to fix it?
