Multiplayer medals not tracking

Hello all.

First time posting an issue like this so please don’t get upset if it’s in the wrong place.

Today, I played verious matchmade multiplayer games on Halo:MMC. I managed to get a few double kill and seven environmental kills in my first game. Since I played so well (and got really lucky) I thought I would continue playing.

I played about 8 more games total and though I would check my medals (towards the verious multiplayer achievements) and to my surprise; nothing registered at all, even though all of my games were on Halo 2A maps!

Anyone know how to stop this happening so my medals will count again?

Many thanks for any replies.

Yeah i would like 343 to tell us whats going on…
