Hello.
Ok, not really an issue, but every time Frostpunk emerges in sales (like current one), it always present among games listed as "Games you don't own". While obviously I own it here, because I played it and when I go directly to game's page, it indicates I own it just fine and can buy only as gift.
Not that I got too many hits in the turret so I don't remember what I bought (Szarik, stop barking!), but it always catches me up like "hey, I wanted to buy Frostpunk... oh, wait, I have it already". :)
P.S. Very nice game, btw, but complimenting games like this always feels odd.

Yeah, I've had that bug with multiple games, on one occasion I mistakenly purchased Shardlight again due to it without the site telling me I already owned it. When I contacted GOG support about it they couldn't replicate the bug, though i got my money back. I'm just really confused by why it doesn't seem to happen on their end.

This has been happening to me too for months now, every time I view a sale page, even though the individual game pages show ownership correctly. Not sure who to get in touch with to help debug the issue.

I found this right after posting here:
