If that patch was supposed to be 1.1.11, i am sorry to report it still does not work. I am using a clear save import from Zero.

Just to be clear it is ONLY the Galaxy achievs that do not work. In-game ones work just fine.

The achievement for "An aenigma no more" still doesnt work

Sorry for the late reply, but progress achievements need to be unlocked again by the player, we can't do that after the fact - hence it might be missing on GOG but showing up correctly in-game. If you do that, and you're at least on version 1.1.12, they should unlock correctly.

I returned to Ao after a looooooong break and can confirm that achievs unlock correctly (when importing Zero data) as of 1.1.12.

Better late than never i guess.

I just got the final few achievements today, but GOG shows I still don't have the ones awarded for clearing the game on hard and nighmare.
In the case of 100% chests achievement, GOG counted it 10-15 min after I got it in game, but so far I've kept playing for about 30 min and the game clear achievs don't seem to have popped into place.
Has anyone else been in this situation? I don't know if I should just wait, keep playing or try clearing the game again on a lower diff. I very much do NOT want to play through the final battle on nightmare again.

EDIT: I replayed the final boss on nightmare again (it was much easier this time, better strategy does wonders) and it popped up instantly. I guess that's the sure-fire way for anyone else running into this issue.
