Strangely, the game is abscent in the activity section. Entering the game I see playing hours, trophies, but on activity only other games.
When I say playing activity I mean this: https://www.gog.com/feed

* As the other subforum is not visible, posting it here (the store page links to here anyway).

Edit:
it's still there, found it, in My progress section, only on Galaxy it's visible I think. But before the problems with games purchased day one that became "invalid", it appeared in the main section in the feed.
