Stats Not Tracked On Legacy Games

So I’ve already read that to fix my issue of none of my bungie halo games stats showing, I need to play them with my new gamertag, but I am unable to do that, as I no longer have halo 3 or halo 3:ODST. I have reach so I can play that, but how can I play any of the other 2?

Sorry, but just to confirm my understanding - you are trying to play the backwards compatible legacy games? Since they are no longer on the Xbox store, I think you would need to find copies for sale online.

No, my stats on halo Waypoint for legacy halo games are not being tracked. Another sub said the fix was to relaunch the games and they will sync, but as I do not have the games anymore, are my stats and progress lost?

I played Halo 3, reach and ODST, and my stats still won’t appear even after a weak since doing it, however my fileshare seems to have survived which is interesting.

I’m seeing other users post about the same issue so I am guessing stat tracking has either been disabled or there is a bug. I don’t remember reading about stat tracking being disabled but it could be in one of the blogs released in the past few months.
