I encoutered a small issue in scramble-mode:
I got a girl though lottery. I tried to train her in the lounge, but her openess didnt raise (the same is true for work).
Was it a Brat?
Later I saw that the same girl was on the recruit list, with the same trait (in this case it was PHD) and same openness (23). I encountered this with some girls in some of my playthroughs but I never could nail down when/why it occurs.
I need better error catching to ensure recruited girls don't show up on the scramblerecruit list then. Thank you.
Normaly i load again and try to get another girl, so the issue is somehow avoidable.
Edit: just had the same problem again: this she wasn't in the recruit list, but her openess was the same: 23. Again no openess gain throuh lounge or work. Adiitional: every girl in the recruiting list at this point comes with 23 openess.
23 is a strange number for openness to 'lock' at, a brat will 'lock' at 20 or 24.
Are you sure it's not around 33? If you have openness locking at 33, this is fully explainable within the game mechanics and intended, for the booths at least.
Edit 2: Did some further testing: the problem seems to occur whenever i get a girl from lottery that has the same openess as the girls in the recruit list.
This shouldn't be, there's nothing in either the lounge or the booths that can refer to or even see the recruit list data.
Don't know if i understand that correctly, but there seems to be fixed values of openess for the girls in recruit list depending on how many girls you have already hired through recruitung (it seems lottery doesn't count) .
This IS correct and intended. There is an intended curve of openness, stats, and costs that occur behind the scenes based on recruited and not lottery/broker/cj'd girls.
Whenever a girl you got from the lottery hits one of theat values the openess seems to be locked (in my case ist was 23 and 27).
I'd need further testing, because I've not found this in my testing, and the only mechanic in the game that 'locks openness' gains is the one that caps what specific acts do--dancing can never boost openness past the natural threshold for foreplay, for example.
