I have the game This War of Mine: Complete Edition on my account. This edition includes every expansion pack ever released for the game.

Currently, the list of achievements on my profile on gog.com looks like this:
• This War of Mine (main game) - 100%
• This War of Mine: The Little Ones - 100%
• This War of Mine: Father's Promise - 100%
• This War of Mine: The Last Broadcast - 100%
• This War of Mine: Fading Embers - 0%

As you can see from the list, I got all the achievements in all the DLCs except the last one, Fading Embers.

The overall achievement rate for This War of Mine: Complete Edition on my gog.com profile is 77%.

On the technical side, achievements work: when I fulfilled certain conditions in Fading Embers, a standard notification (the name of the achievement and its icon) was displayed at the top of the screen. But these achievements are still not taken into account either in GOG Galaxy or in my profile on gog.com.

I sent a request to GOG support a few weeks ago, but no one answered me... Please help me fix this strange problem.

Do you know the exact achievements you should have unlocked and roughly when you unlocked them?
In theory they should work correctly, also I have never heard that the achievements aren't unlocked after seeing the pop-up animation.

If I haven't forgotten anything, I actually got almost all the possible Fading Embers achievements:
• Diary: Good Neighbor
• Diary: My dear Ruben
• Diary: Fool the Crow
• Note: The truck is ready
• Note: Fortify +
• Diary: The Custodian
• Note: The Colonel
• Diary: Innocent children
• Note: The Fence
• Diary: The Janitor
• Note: Burn'em all

I marked with a plus the achievement that I received yesterday. I received others earlier, I don’t remember the exact date.

As far as I understand, I have only one achievement that has not yet been unlocked: “Epilogue: All the way” - this is the latest and most difficult achievement (getting all six possible endings).

And yes, I also encountered such a problem for the first time. It’s doubly surprising that I received achievements for all previous DLCs as usual and there were no problems with them.

This is what the list of achievements looks like now: s8d8.turboimg.net/sp/6427760cf4e4214834ad64a4501b53d5/achievements.jpg
