Yesterday when I looked at my collection I had 97 games, and today, after snagging my free copy of Shadow Warrior 2, my collection only has 96 games, meaning two games have left my collection since yesterday. I have no idea what they are... has anyone else experienced this?

Yeah, something is up. I seem to be missing quite a few things, if I remember the number correctly. For example Freedom Force vs The Third Reich is gone from my collection, but still is marked as own when I find it in the store. This is bad.

Have you, by any chance, bought any GOG game outside of GOG?
There have been incidents in the past about game codes purchased using stolen credit cards and then sold in third party stores.

If that's not the case, you may try to refresh your account:
https://www.gog.com/account/refresh

If the problem persists, I think it would be better to contact support. Interesting, that game is correctly shown in my library for now.

And this is the part where I sound like Shatner in The Twilight Zone, because it's back here as well, but I'd swear it wasn't there a few minutes ago when I checked.

I still have this issue though, that my avat doesn't display next to the "Account" tab like it used to, and the tab isn't showing me the numbers next to games and movies like it used to.

I have the same issue with the appearance of the account submenu. I don't know though, if it's intentional or just a bug.

Same for me. Then again, GOG's page is breaking more and more for me in general. I don't see the news section, I don't see how much games cost below the large banner (everything above is correctly displayed). The "discover games" section is probably broken as well, as it is cut off and I see only the names of the games as well as the platform. Sometimes it doesn't load properly, so all the game pictures below the banner are completely black. It's just a broken mess, that I won't touch until it's fixed.

Hence Why people want the broken website addressed before they play around and break other things with it.

No, I haven't bought any games outside of GOG. And refreshing didn't correct it. Hmm...

Yep,bug.Mine says games,nil.

It gets better. It's back for me now, but now there is a discrepancy of 29 games between the number that shows in the drop down menu and the number that's displayed on the top of my library. Which is the correct number... or at least the number of games currently in my library, but I'm no longer even sure if something isn't missing :P The hell's going on here?
