Well, it appears that my countless hours of Halo 2 and Halo 3 have gone to waste as my profile now indicates I have not even played either game, when I have as you can see by following this link: Bungie.net. Is this perhaps a bug? Someone should look into it. I feel like I have been cheated out of my hard work.
Try playing a game on halo 3 and see if it updates.

Yeah, I determined it was an issue with me having changed my gamertag and then having not played Halo 3 since it was changed. Just played it and it’s updated now. Still a shame about my original Halo 2 service record though. I guess that’s never coming back 
Figured thats what it was. Glad to help.
The same for me with Halo Reach & Spartan ops

I will try for Reach but I’ve played Spartan Ops yesterday & I have anything in waypoint
Make sure its a matchmaking Spartan Ops game. That might trigger it.
