Skulltaker Halo CE Iron stuck in Done: Unlocking HELP

[OldObiWanKenobi]

So I buy an Xbox for this game specifically, only to have the very first achievement stuck in "Done: Unlocking...." mode. I've tried all suggestions by Microsoft (Removing account from console, uninstalling/re-installing game, forcing a profile sync) and nothing. Not a good way to start the game, and not much faith for trying to get the other achievements. What the what? I've been xboxing since day 1 and never...NEVER had an achievement stuck like this. Can anyone here help me? It's really really frustrating. Is this game really that buggy?

An update to this, because I'm sure I'm not the only one who has or is going to experience this. I still didn't get the Skulltaker Iron achievement. I've finished Halo CE Anniversary getting all the other skulls as well, and my main worry has been rectified: I got the Headhunter achievement for getting all Halo CE skulls, even though this one was stuck in 'Done: Unlocking..." mode.

 

BUT, and there's 2 buts here: first, even though I RECEIVED the Headhunter achievement for getting all skulls for Halo CE, after finishing the game, this skulltaker Halo CE: Iron achievement has gone from stuck in unlocking mode, to not being registered as an unlocked achievement. It says I didn't get it, but yet, I got the headhunter achievement for all skulls.  Like to know how they figure that one, but not going to complain as my main worry was this one affecting the achievements for all skulls for all games. I'm going to try and go back and get the skull and see if it registers this time, now that it's saying I didn't get it at all.

 

Second BUT, Now the first achievement in Halo 2 for the first skull is now stuck in Done: Unlocking....The fun never ends. I only hope for this one like the Halo CE one, that it registers as done when I get all the Halo 2 skulls. But honestly...a bit buggy is an understatement.

I have basically the same situation.  The very last skull I needed in the game was the Catch skull in Halo 3.  I now have 3 achievements showing 100% but locked:  Skulltaker Halo 3: Catch, Witch Doctor (all Halo 3 skulls), and Thrones of Bones (all skulls in Halo CE, Halo 2, and Halo 3).  They have been this way for almost 2 weeks now.
