Hey, we've had some reports recently that some achievements weren't working after the latest game update.
I've had a look into this and it was an issue on the Steam backend where unfortunately when adding the new Chinese translations for achievements some were added in the wrong place. This meant that when the game tried to unlock that achievement (when playing in any language) it wasn't able to.
The achievements impacted by this were:
Lumberjack
Overkill
Heartbroken
Postwoman
Indecisive
The fix is now live and Heartbroken, Postwoman and Indecisive should automatically unlock next time you load a save file where these events have occurred as their progress is included in your save data. For Lumberjack and Overkill you would need to redo the requirement for these in combat, sorry about that. There isn't a patch for the game as it's a backend Steam fix for this. After making the fix I closed and reopened Steam (to make sure it refreshed) and was able to unlock all of the above achievements when testing.
Thank you
Tom
