Sorry if this is a known issue. I just got my XBox One and started playing my first game (Battlefield 4). I've already gotten all the achievements on the 360, so clearing the game was no problem. However, on my achievements page in XBox One, I show 43 (out of 52) achievements. I have a score 1040/1240 (points wise, that is my last 8.5 achievements that are missing). Trueachievements.com (which I use to track my achievements) shows me with 49/52 achievements. However, in-game, I have all the achievements. Do I need to recover my gamertag to get it to sync up the popped achievements that don't seem to be counting?
