It took a long time to unlock a game. Only one thing missing ... But I went to see that they are all unlocked in one day and at the same time ...

I have two full games and it's normal the day of unlock and time, but only one game has a bug, I have not used any of these programs to cheat.

I contacted Steam / Valve and they said it might be an overlay error and click the tab to see the profile info ...

Honestly, they know nothing about the problem, but it's bad because I know there are people who use cheating to unlock and that was very similar to my problem and timeline.

Observer: I have a shared site about achievements and there appears my unlockings on the right date, only on Steam that has changed, I do not know why.
