I've had left alone my personal GOG library's shelves. They've always been in the same state, alphabetically sorted.

I noticed recently a missing gap on my shelf between Icewind Dale and The Incredible Machine.

Was there a game recently deleted -- even retroactively from owners' accounts -- that started with the letter "I"?

dark fall 2 has gone walkies because nordic is delisted again

Indeed, it is missing from my Library. Even though I owned it, and even though the other three games (Black Mirror 1&2, and Dark Fall 1) are still there.

Since when does a publisher being delisted mean a game being deleted from owners' accounts? It's never worked that way. Neither on Steam nor GOG.

its a bug
this usually happens a game gets delisted it suddenly goes walkies
its usually fixed withina day but because its christmas tomorrow i dont expect a fix before next week

It was taken down as a bug, it should still be there. Contact support, they'll sort it out .

Were you in the beta for The Witcher Adventure Game?

On GOG, there has been a bug for quite a long time that temporarily removes a game from accounts when the game is also removed from the catalog. 32 Nordic games were removed just yesterday and ended up being removed from all accounts as well. The GOG staff reinstated the 31 of them (as far as I know), but they probably forgot to reinstate Dark Fall 2. Unfortunately, the GOG staff won't be working tomorrow and I don't know whether they will be working on Friday, which means that people with Dark Fall 2 might end up waiting till Monday to have the game reinstated on their accounts.

Okay, good to know it's just a bug.

I can wait until whenever. Those aren't exactly games that were in the "top 50 to-do" in my backlog of games.
