Achievement Glitched?

When to pop like that it a glitch. It not same glitch you thinking. This kind glitch either pop early, Pop late or wrost it never poped at all. Go to your XB1 and compar to me. Some achievement at stuck at 93% on one achievement. And on 96% on another achievement
on warframe. And on the one. There is sever glitch. That takes days to unlocked the achievement in said game.

Once you have unlocked an achievement on a game it can not be removed from your profile.

Glitched achievements are down to the developers to fix,not Microsoft.

Do agree that glitched achievements are annoying though

I too have a glitched achievement with "Finders keepers" I have collected every chronicles and it say's on the collectible tab I have all of them, yet on the achievement page it says 97%.

No idea how to fix, these glitched achievements, I think they're Microsoft's cloud fault. I have 3 glitched achievements at the moment.

I've read on x360achievements.com that the achievements are glitched. I myself didn't receive the achievements after collecting all of the books, it's apparently down to a bug that makes the achievements glitched if you've played co-operatively.

No one knows how to fix these glitched achievements. It's Microsoft's cloud servers that are at fault. I have three glitched achievements on two different games.
