I think I have almost everything.
Rachel, Debbie and Amy are at maximum level.
Cassandra is at 2, but she won't let me anymore (there are several actions that she won't let me use even if they don't appear in black and white).
What I lack:
I could not get the code to enter the girls' bathroom, with
priti I have not managed to speak at any time, nor has he given me the option)
To enter the rooms I went through Rachel's window (once), she has given me no other options.
That's it? or am I missing things?
I looked through your save. All looks fine you seem have ended all what could be possible in this release.
But. Be true , you cheated a little bit ? The horniness and influence points in your save are at an astronomic hight and not yet really reachable at this version of the game.
As your remarks :
Its impossible for HM to enter the girls bathroom (showers) and girls lockers in the gym same the girls dormitories are not allowed to enter for the HM until the option for changing the Headmaster privileges in the schoolrules or an event to get the doorcode is is added to the game (but may be possible in a later future release update)
about Priti and Rachel, if I didn´t got you wrong:
If you start the quests "Priti´s password" and "Priti´s nude pictures" normally you can talk to Priti and call her in HM office. What was no problem for me to play the game through myselves if only cheat a little bit at the money.
If you never couldn´t call Priti in HM office or speak to her in the hallway is a riddle to me.
So please post more about your difficulties with Priti and Rachel.
The reason could be if there isn´t an unknown bug in this release:
You had switched events from "off" to "on" in cheating menu ? (the 2 ending events for loosing the game are shown only if you did switch before)
That may prevents some things to be happen in HM office , on patrolling or at teaching classes.
I took a second nearer look at your save and switched the "All events" to "off" and corrected the horniness and influence to normal.
The result: several quests are not ended yet. You have to follow Rachels route a little more. What may help. I am too tired now beeing awake since 28 hours to play all needed steps through yet. But here is a little bit corrected version of your save for you to give a try yourselve solve the missing with Rachel and Priti.
