Acheivement and name plates not unlocking.

This may be noted by others, but I figured I’d post the issues I’ve experienced with unlocks and maybe someone can help me out with some suggestions.

I’ve beaten the Halo: CE legendary campaign playlist. The playlist shows as completed in game, every missions shows me having beaten it on Legendary. I have only gotten achievements for beating it on Easy and Normal, and likewise only gotten the nameplate for easy and normal. I have also gotten all skulls (and all skull achievements) but not gotten the nameplate unlocks for that.

I’ve beaten Halo 2 legendary campaign playlist. The playlist shows as completed as well as each mission on legendary. The achievements have not unlocked for even beating the game, let alone any difficulty. I have gotten all skulls (and achievements) but not any of the nameplate unlocks.

One of the Halo: CE achievements is listed as “Done! Unlocking…” for a few weeks now. The rest of them are still in partial state, even though all the requirements for them have been completed.

While I would like the achievements, I would also like the other unlocks. Would it be so tough to change the unlock reqs for nameplates and the like to be from the game? Instead of based on the achievements?

I’ve read that at least one of the past patches was supposed to fix this but it hasn’t. Anyone else have this problem? Anyone with any solutions or ideas?
