mrkgnao: Can you list which games?
My last flag was on 8 Feb, but then I don't think I own anything that has been updated since (except the Yellow Mask demo).
UPDATE: I just now (10 Feb 23, 20:02 UTC) got a flag for Brigador, so it seems update flags are not gone.
LiqMat: So far, I never received update notices for:
1.) Witcher 3 (for any of the December updates)
2.) Blade Runner Enhanced Edition
3.) Brigador (finally came through today from the Feb 1st update)
I am sure there are others, but I'm not digging through hundreds of games in my library.
To the best of my knowledge, neither TW3 nor BREE not getting update flags is a new issue. I believe not getting an update flag for these games is the normal state.
There are a lot of games on GOG that
never get update flags,
by faulty design. These would be the majority of the games that are classified as a "package" rather than a "game" in GOG's catalogue. There are hundreds of such games and none of them
ever get update flags. They are still a minority, but they nevertheless number in the hundreds. I know for sure that TW3 is one of them because I own it. I do not own BREE, but given that it is classified as both a "package" and a "game", thus having two different IDs (the root of the problem), it is a fairly safe bet that it is one too.
The only way to keep one's library 100% up to date vis-a-vis GOG's servers is not to depend solely on GOG's update flags, but proactively check all one's games from time to time. I know of three methods of doing that:
(1) manually compare all one's files to those on GOG every so often (feasible only for very small libraries)
(2) check GOGdb's logs on a daily basis to find missing flags (possible, but sisyphean)
(3) use an automated tool to regularly compare all one's files to those on GOG every so often (I use gogrepoc, doing a full update about once a month and I always find missing updates)
That's the way it's always been on GOG.
