Halo 3 odst

So when i look on my account here on waypoint it tells me that i dont even own and have never played Halo 3 odst even though i litteraly bought it a second time so i could play it on the xbox 1 and i have completed around half of the campaign but still nothing is showing up

ODST for the X1 is only available via the Master Chief Collection, it doesn’t have any ties to the original ODST game. If you have changed your gamertag at any point then your stats will still be tied to your old tag. If you can, load up the game and play while connected to Xbox Live. Your stats should sync to your new tag shortly after that

Yeah i know and i have it via the collection and i have not changed my tag a singlw time yet it does not show up under my games in the collection here on waypoint
