There doesn't seem to be a pattern.

Sometimes the "Goodies Collection" (Cyberpunk 2077, Spring Sale #1 and #2, Witchter) appear, sometimes they don't.

The only consistency is that they never have a grid image.

I wonder why they just don't stick on the library, like the games

EDITED: Right now, they just disappeared from the client library. Really weird.

Some people stated that these don't show since tecnically they are not games.
I am honestly more surprised that you could see them in the first place.

A separated section for "goodies only" or GOG movies would be nice.

I noticed this as well. For most time it remains hidden, but sometimes like to pop up. Not a huge problem IMHO, but it's there.

Let's hope they do that, since behoviour of showing up / disappearing is rather annoying. It's really weird isn't it? Makes me wonder what they're doing.

It hasn't popped up in my library for quite a long time now. It's just a simple bug, nothing more. Something triggers when it shouldn't. Not a huge problem anyway.

Just happened again.
