Somehow I didnt unlock the "A light in the dark" achievement

[Veir]

Hello

I dont know if its a bug or Im just missing something there, but I unlocked 11/12 achievements and the last one I cant unlock is the one named "A light in the dark", which supposedly wants you to unlock all of the achievements. What did I do wrong here? D:

I have the same issue, so confused

[Veir]

Can we get answer from developer? xD Like, we cant solve it by ourselves

Finished the game today, everything unlocked for me.

Same, I don't know where it comes from.
Did my first run offline (still unlocked the achievement though), and did it online again just in case.
Also did the new ending.
That disappointing to see a new ending added without fixing this bug...

Yeah its dumb, I like to 100% games I played and now Im stuck with this one being unfinished

Same problem here. I've got the other eleven achievements and I've done all the endings, including the add-on... Can't get "A light in the dark".
