Xbox achievements have disappeared

If it's xbox one games then it's a glitch that has been happening for a couple of years.Had it happen to myself where i just lost over 200k gamerscore.

No one knows why it happens but it should just correct itself within a few days.

Everyone i've encountered with this glitch has got their gamerscore back to normal,including me,but like i said,it could take a few days.

Hi

This is probably only a system glitch if you give it a few days this should correct itself.

If the games showing missing gamerscore are One games, it's a glitch that happens randomly. It usually fixes itself within a few days.

Hey there northernhorns22,

From the looks of it, it seems like your gamerscore has been restored to the correct amount. Let us know if you're still seeing achievements not popping and/or your gamerscore being reduced.

The Xbox Live service validates the unlocking of achievements and, though rare, delays can occur. To learn more info, check out this Xbox One Achievement support
