short version: achievements are stuck

for some reason when I ran through the campaign of halo 2 on legendary it decided it was going to unlock all of the other completion achievements too and now all of these (completing halo 2 on easy, normal, heroic and legendary, and completing every campaign
on easy, normal, and heroic as well as two skull related achievements for some reason) all tried to unlock at the same time and are stuck in done ... unlocking. I've already tried deleting and reinstalling my account and that led to a whole other issue where
apparently my cloud save of the game became corrupted and now I can no longer get the game to sync to the cloud. Through some miracle that I may never understand the game somehow still works completely fine without the cloud sync and even though I'm playing
the game in offline mode now I can still connect to and play matchmaking games. This is without a doubt the strangest thing I've seen my xbox do.

So all of that out of the way I'm understandably hesitant to try removing my account again because I apparently can no longer pull from the cloud to replace the save if it gets deleted. To be perfectly honest though I don't really care about the achievement
itself I'm just doing it to get the special armor for halo 5 and I've yet to find conclusive evidence one way or the other as whether unlocking that is tied to the legend achievement or the your service record for mcc (which is stored on halo waypoint). If
someone knows for sure it's tied to the service record than honestly I'm ok with the achievements being stuck like this forever, I just don't want to keep going through the rest of the games on legendary if I'm not going to get anything for it. Sorry if I
sound a little angry, I don't mean to be it's just been a long day trying to fix this. Any help anyone can give is greatly appreciated.
