PaterAlf: I got tired of waiting and now use a script that fixes the problem:
https://www.gog.com/forum/general/fix_for_owned_games_not_showing_in_promos Pointed GOG support to that solution when it was posted too, they said they made the devs aware of it. But we all know how GOG time works when it comes to fixing something... as opposed to breaking it.
BeatriceElysia: I was kind of expecting a Spring Sale, you know.
Same. I mean, there was a major sale each March since they started having sales other than Summer and Winter ones, and now with the FPP going away at the end of the month definitely fully expected one to sort of send it away, give one last chance for people who want to make use of it (not that anyone should, as that just encourages publishers to keep setting prices above base, GOG's FPP did nothing against the practice, or if anything made it more tolerable for some instead of nurturing a backlash against it). And with the FPP ending on the 31st I doubt there can be a sale starting next week and lasting past the end of the month, and major sales usually aren't just one-week affairs. Then again, wonder if the FPP ending is just why there's no major sale now, they want to wait until they won't have to deal with it anymore and will start it on April 1... Which is an odd date to start something...
