Hello, the game shows as updated, but then nothing is marked, when I open it on the shelf. Why doesn't GOG show what exactly has been updated anymore? I do not want to download everything again. Who knows, maybe it is only a new Linux version and I would do it for nought.

This was the update. The update notifications have been broken for some time and are only getting worse. It won't be fixed until GOG "updates" the Library pages which is one of the things they are working on next.

Ah, so that's what it is. Thanks for the info! Much appreciated! Yup, the notification system could definitely use some polish. Cheers!
