JudasIscariot: The developer sent us an update yesterday to the game and we've published it today (30.01.2019). Can you check if the achievement in question works for you now?
Alexim: Thanks, I don't have the game personally but I asked everyone I know that have the game, and maybe even Ingsoc85 can help us.
And Judas, for the "fast fixes" series, there would be these two small errors to be corrected in the description of the achievements of the game
BattleZone 98 Redux: "Red Arrival: Complete the Red Arrival mission on Medium difficulty or above
or above." and "Bring it Home: Complete the Bring it Home mission on Medium difficulty or above
or above."
Fixed, thanks for letting me know :)

Ingsoc85: It didn't unlock for me but it may be because I unlocked all other achievements two years ago and since "Lol, Really?" is tied to them (the description is "complete all achievements") it may work for people who unlock them since the patch and not before.
Well, it unlocked for someone because our achievement tracker, for lack of a better term, suddenly registered that achievement as unlocked and it wasn't us unlocking it :)
