The game's achievements have been broken for a week now. The summary tab shows them without an image and the progress tab says I'm at 100% now, which is obviously a bug.

Same here

Same here why no fix yet wtf

It's almost as if this whole system was half-implemented nonsense at best.

Though, it's probably a low priority issue compared to the other issues of GOG Galaxy.

I have similar problem. My last Rouge Trader achievements were gained on 1st October 2024. After that, I haven't seen any new ones (and I know, I should have more).
I have also started to wonder, if this is a GoG problem, or the Owlcat problem, as the same day (01.10.2024) there was a hotfix for Rouge Trader (version 1.2.1.12). Maybe it is just a coincidence.

Anyway, I hope, that this issue will be fixed soon.

Similar issue.

I earned my last achievement on October 7th, and since then, nothing, despite completing several "unmissable" story-related ones

Update 12/10: Went around digging in game log files, found out the achievements are logged there, but do not get passed to GOG client

(and plenty more instances of similar error are logged)

So I am guessing this might be a GOG problem, that it is not responding to what the game is trying to send?

Interesting findings, but one thing is strange for me. Last update of GoG Galaxy is from 24.09.2024 (version 2.0.77 Beta), while people are reporting, that their achievements stopped counting in different time periods after this date. So, is this like a 'counter', that for every person, for some time achievements will be working, but later will stop? After certain number of days, achievements, hours played?

Also, is this some kind of connection issue (API is unable to get communicate properly with GoG) or some kind of problem with data itself (API can communicate with GoG, but it is unable to find data, that is looking for)?

It would be nice to know, if this bug is registered somewhere (so, if GoG team noticed it)

I am not sure how assertive Galaxy is with its own updates, so it is entirely possible people were running on old GOG Galaxy version (especially if most people just put their PCs to sleep, so no restart, I assume the update check happens when the program starts), and that the new one somehow broke the API calls.

The stuff in the logs reads to me like a failed function call, though obviously that is just my generic coding background, I have no idea how Galaxy or Owlcat games are coded in this regard.

Seems like maybe Galaxy started expecting some argument that the game isn't sending
Galaxy.Api.GalaxyInstance+InvalidArgumentError: 'name' is empty

I think I have found the solution to this problem. It seems, that for some reasons, firewall was blocking some of GoG functions (although, usually applications are asking for adding them to the whitelist, when they are trying to send/receive some traffic and firewall is preventing them to do so).

I have found this article: https://support.gog.com/hc/pl/articles/360012311173-Osi%C4%85gni%C4%99cie-nie-zosta%C5%82o-odblokowane?input_string=osi%C4%85gni%C4%99cia&product=gog

that is instructing to add lisetd below filest to the firewall whitelist (I have added it both to receiving and transmitting whiteslists, just to be sure):

1) Game main file (in our case wh40krt.exe)
2) C:\Program Files (x86)\GOG GALAXY\GalaxyClient.exe
3) C:\Program Files (x86)\GOG GALAXY\GalaxyClientService.exe
4) C:\ProgramData\GOG.COM\Galaxy\redists\GalaxyCommunication.exe

Then restart GoG Galaxy.

The effect is, that after launching game, after few minutes, GoG Galaxy seems to give me the achievements, that I have done, but were missing. Proof in the attached files (you can compare them with attachments from my previous posts). I hope, this will help others, who have the same problem.

Only two things are comming to my mind now, that may help:

First, would be just to disable firewall (for just few minutes, for testing purposes) and run game from GoG Galaxy. Your achievements should be loaded as the game starts (and maybe load game from your last save, but I think there is no need to do more). Give it, lets say, 5 minutes, than look at the GoG Galaxy, both on the general tab of the game and the Progress tab, where the achievements are listed. If something new will appear, it means, firewall was somehow still blocking something. Maybe check once more if the both incomming and outgoing traffic is allowed for files mentioned in previous post or search if more of them are needed? But you will at least have a lead.

Second, would be to upgrade the GoG Galaxy version. I had problems with it, as the auto updater was stuck, looking for update forever, so I have decided to just download installer and run it (as was proposed in some forum post). It did not made any difference, as my version was the newest, but I guess trying that step will not hurt, maybe something was refreshed in the background?
You can also try to just reinstall GoG Galaxy at all, uninstall, clean registry with CCleaner or sth and install it again, from zero.

Aside of that, I don't recall doing anything more to solve this problem.
