Got a link for this? Star Wars: Knights of the Old Republic received an update (on Steam I guess?), but that update hasn't shown on GOG?

Looks like 1.4.6 just dropped for the Windows version. Hopefully Linux and Mac follow shortly.

Blackwell (The complete series) - missing 2021 update for modern monitors on Steam

Gemini Rue - missing 2017 and 2021 updates for modern monitors on Steam

Golden Wake - missing 2020 update on Steam

It is sadly becoming clear Wadjet Eye Games couldn't care less about their GOG customers. Every question about the updates coming to GOG is just ignored by the developer on Steam forums.

Is Cardaclysm: Shards of the Four listed ? The latest patch isn't on Gog .

Spellforce 3 and its expansions (Soul Harvest and Fallen God) don't recognize each other when purchased on GOG (this works correctly on Steam).

This means, for example, that you can't use all the factions YOU PAID FOR on skirmish and multiplayer (e.g. no way at all to play Trolls vs. Dwarves).

See the thread here:

Both GOG and the developer are aware, as far as I know, but they haven't provided a solution and probably won't ever do. It's simply unacceptable, a total rip-off.

While lack of Linux ports of LL and 33 can be excused with Feral Interactive's hostility towards DRM-free the fact that Exodus port isn't here - which afaik is made by the original game dev's (4A Games) - is inexcusable.

That and have a claus of sorts or whatever that allows if troubles prevent it they can have extra time if the reason for the delay is justifable and/or is a indie team

Good news:
Dave Gilbert was so friendly to reply to my question about this within seconds ...

"Hm. They may be right. GOG used to take care of that stuff for me, but not anymore. I thought I updated some of those myself but I might not have done it right. I will look into it!"

Allegedly some of the updates in GOG's product manager (probably not official name on GOG, tho it is named more or less like that on Steam's internal system) need to be confirmed manually by GOG staff while others are pushed automatically and propagated to content delivery system (for users to be able to download it outright) as soon as they are uploaded by a developer.

Whether this is true or not it is a fact that there seems to be not-so-imfrequent occurence when updates seemingly uploaded by developers to GOG's system don't find their way into general user availability and they don't get propagated until manual intervention after multiple complaints several weeks or longer later.
This situation both creates an unfair predicament for users as well as makes devs look bad while it is not always their fault.
Seriously, GOG should really pull their sh*t together already... Question:
If a game on GOG has discrepancy between versions available to GOG Galaxy users, and offline installer version-to-version patches, should it be on this list?
I am talking about a predicament where there any many builds of some game (because for example it was updated multiple times since it's launch on GOG) but version-to-version offline patches are far less than the number of builds and every few versions to update you need to download the entire full installer (thus do a full reinstall) as the patches simply ommitt some versions.

It is true. I have been told personally by a dev. Usually the branch in which the game only gets published after GOG confirmed should be used for unknown devs ... however it seems to happen sometimes that even known devs who already published on GOG will accidentally get pushed to this branch. It just happened recently with Strangeland (this has been fixed quite fast and devs can now publish without GOGs help which is the reason why several Strangeland updates already have been released). I do agree that such mistakes should not happen ... at least not as often as it appears to be the case.

Mechanicus is now fully updated for Windows/Linux/Mac.
All platforms are now 1.4.6.1, including DLC.

Ring of Pain here on GOG doesn't have the paid soundtrack DLC, which was released on Steam back in October 2020.

Terraria is missing quite a few soundtracks.

From what I could find, it's missing the volume/discs 3 and 4 if compared to the first OST DLC from Steam (volumes/disc 1 and 2 are already included as goodies), and it's also missing the entire Otherworld OST, also available on Steam as a DLC.
