Until yesterday I was able to see my friend's Frostpunk activity and achievements, but now the feed is empty and the game isn't visible in the profile. URL that used to work now returns 404:
GOG.com/u/__PROFILE__/game/1648559910

Seems like achievements have been removed... hoping only temporary (maybe the update is in progress?).

Yeap, page with FP achievements is gone, activity feed cleaned.
