I noticed a couple weeks ago that the game Satellite Reign was missing...bought the game years ago. Tried to contact GoG with 3 emails but no response. Anyone else missing any games? I'm worried about all my games now...also haven't bought anymore since.
Btw this was in my games library not Galaxy...though I did install that and checked about a week ago (wanted to try out FTL Multiverse, Great mod).

Did you try https://www.gog.com/account/refresh already?

Maybe check that you haven't accidentally hidden the game in you library...

At least I have Satellite Reign in my account, so at least that game is not missing for everyone.

It may be very hard if not impossible to track if one is missing any games he's bought before. I can check that with gogrepoc.py tool though, as it would mark any such vanished games as "orphaned" (provided you have downloaded the same game before).

Thanks guys...yeah...checked hidden games a while back, never understood what peeps mean by that refresh link....though I did click on it. Did a search about missing games...seems at least 3 others had this issue. I think 2 were related to galaxy updates...mine is not.
I used to just download all the games and keep them in a removable hard drive.... still might be there, don't like the idea of going back to that not to mention the implications. About 5 games i wanted to get so far that were on sale (I'm cheap and only buy stuff under $10). Wonder if I"m missing more...not like I kept a list.
Hope they figure it out...you all stay safe.

It's a link that was at one point shared by support and made its way onto the forum. It doesn't offer any clue as to what it's doing, but loading it will make missing games appear in most cases. Since it didn't work for you, be sure to reply to your support ticket and mention that. I do. I keep a local wishlist + owned games list. Precisely because I heard one or two others on the forum say games vanished from their library. So if the count is off, I'll notice. Thus far, I've only had one missing game, which wasn't added 2+ hours after purchase. The refresh link fixed that right up.
I've also had at least one wishlist item silently disappear, when the bundle in question stop being sold because a newer one was released.
Additionally, I locally back up all of my order receipts, on top of archiving every order receipt e-mail.

Good luck getting this sorted.
