Just finished my 3rd playthrough of this (2 on the steam version years ago) and am missing 2 achievements:
Meticulous (I used a guide to make sure I get the notes)
That's much better! (I finished the game, so since this is a mandatory step to said ending I should have gotten it)

Anybody else gotten those achievements ?

I got the Meticulous Achievment, so its not broken.
I only miss 1 Achievment which is from gog "Legendary"-Status + this achievment doesnt show me a %-Number who many solved this so i think that its broken. Seems that is the "That's much better!" Achievment

Also missing « That is much better! » achievement. After starting the generators the game hangs with RT standing in front of the console and I cannot move it. I can acces the in-game menu just fine. All other achievements work for me.

I got the Meticulous achievement, but That's Much Better is definitely bugged. I have a save right before you have to activate the generator which triggers the achievement, just have to run over there and activate it.
Game will kinda hang (you can't move or do anything, but it is still running), if you alt+F4 out of the game, start it up again and continue it has now saved AFTER powering the generator up and AFTER the achievement trigger with no achievement triggered.

I can send you that one if it helps ?
