As a followup to my earlier query, I finally got around to finishing the first part in my Steam purchase and besides missing the achievements, I also had lots of missing / variable not defined errors in 2 parts of the game. First, when Cam gets returned to a cell I got many errors that had to do with finishing choices in multiple chapter sex scenes. It looks like at some point
Perverteer added variables to track creampie, body, facial, etc for almost all of the sex scenes without first default declaration of False for all of them so they came up undefined at a certain point in the code that apparently checked for them.
I went through lots of gallery scenes and some early chapter saves to see what the scene was all about and pick what might be correct answers for them and added the value in the console. I added lots of True of False but I don't know if that is the right value or if they might be numerical or any other combination.
There was another section shortly after that had another large quantity of undefined values that seemed to be related to did the MC sex up this individual at this time. Once again lots of True and False values were used in the console and I was able to get ejected from the hanger successfully at the end of the content.
Another thing I noticed was some of the gallery scenes seem to end prematurely, after going back to saves to see the scenes as well. I don't know if they are ones that might need to jump to the extras scenes to finish but I thought it was odd and I would consider it broken.
So that whole process took some time and I managed to get about 5 achievements out of the work. If I want to get the other 55 or so, I will have to play the first bit over again.
