I logged in, went to Halo Reach to see my old stats from back in the day, and it says I’ve never played it before. Any reason why?
If you have changed gamertags since you last played Halo Reach, then your stats won’t have synced up with your new tag. You would need to jump back in and play while connected to Xbox Live - can be campaign, forge, multiplayer, customs - and everything should sync up correctly after that.
Mine Still hasn’t fixed itself…
