Hi everyone, as subject says, I've purchased months ago New Colossus, installed about a week ago and played it without problems for a couple of hours in variuos days, but suddenly today it does not show up anymore in my GOG Galaxy.
Not only it has been delisted from "installed games", but it disappeared from my library!
What can I do? I already tried to go to Galaxy settings to "add friends and games" and scan for GOG games or "add manually" but it doesn't find any game.
Note that if I launch the game from the install directory, it start without problems, so at least I can play, but I imagine that the achievements and the save game cloud sync will not work anymore.
Note also that if I go to my account from a browser, the game show up regularly in my library...
Thanks!

Hello I also have the same problem! The game disappeared from my Library and Owned list altough it shows in GOG Galaxy on browser.
I bought the game in February this year as a part of Wolfenstein Bundle along with New Order and Old Blood

Hi, if it helps, I solved by uninstalling Galaxy 2.0 that I read it often have such issues, and then installing Galaxy 1.2
I followed this guide:
https://www.gog.com/forum/general_beta_gog_galaxy_2.0/how_to_keep_galaxy_v12_client_and_avoid_the_forced_v20_beta_update/page1

Surely, using an old release of an app that keeps also asking to update by showing a fixed message in the lower part, is not the best, but for now (at least until I read of a better release of Galaxy 2.0) I'll proceed this way.

Note also that even in the Galaxy 1.2, for a strange behaviour of the filters, some games didn't showed up until I selected the "All my games" in "Library" menu: by default it showed "Windows" games (my system) but it only showed Windows "exclusive" games, for example if a game was compatible with Linux or Mac, it didn't showed up.... Surely it's not a behaviour that one can imagine... By selecting Windows I expect to see all my games compatible with Windows and not exclusives...

I hope it may help you and others with same issue...
Bye!

Thanks for the tips! Galaxy 1.2 surely better (there is many issues in 2.0 and functionality degrees).
