Achievements unlocked in-game are showing as locked in achievement tab

To fill in some "blanks". Actually, every Achievement Unlocked has a few methods of the order it appears. If you Unlock an Achievement and view it from your own Profile it will simply show in the order the Achievements were Unlocked.

If you Compare Games with someone else (Friend or not doesn't matter), it will show both the combination of your Achievements and their Achievements but in the order they Unlocked the Achievement/s.

If the other Player has Achievements Unlocked that you do not, it will show in the order they Unlocked the Achievement/s with yours showing Locked directly across. If you have Achievement/s Unlocked that they do not it will be at the bottom of the Compare Games
in order of which the Achievement/s were Unlocked from your Profile.

Look at your achievements tab for this game. Does it show the progress as complete but the achievement isn't unlocked or is it straight up 0% with nothing?

if the game sent the criteria out to 'pop' the achivement, you'll be fine. fire up the achievements App and have a look at the two achievements in question. they'll show as unlocked, locked or 'done unlocking' - LIVE is back up and running now.

Unlocked - You got the achievements! hooray!

Locked - Game has failed to communicate unlocking of achievements - load an old save and redo the criteria

Done unlocking - Wait 36-48 hours and they should unlock. sometimes the system gets a little caught up.

That's strange.

Is the achievement showing unlocked on the console or are you seeing it pop in game and then locked in the achievement section?

I had that happening with the Forza level achievements and they unlocked about 20 minutes later but it was only that game so I assumed it was just a glitch with Forza.

Hi, I have the same issue. So I played on the 360 the game South park S.T.O.T yesterday.

and unlocked some achievements. they did not show up on the achievement list

example (achievents unlocked 0/50). but when i enter the achievement Tab. the achiements pictures are unlocked with the date. Then i pressed the guidebutton and went to achievements South park and pressed X to delete Game History. The achievement Tab South
park was removed but when i restarted

the 360 console the south park achievement tab was back again with the same issue. i tried to redownload me profile but it did not help to resolve the issue. today i unlocked another achievement from south park and it had the same issue. Then i Started up
the xbox one and the achievements app

gave me this errorcode 0x87c40011 . hope this gets resoveld soon.
