What about editing saves? Is there a tool for that?

Download the ''.069'' one. Open it, load your last save file. Keep in mind ''Autosave'' is filesave1 which means for the save you're gonna edit you have to add +1. Lets say if you're gonna edit save number 22, you have to load filesave23.
Now up there there is an ''advanced'' segment. Click and check variables.
Now if you type ''Sabrina'' in the seach, you shoul come across everything related to her.
You can change her affection and corruption, I would not recommend event touching the ''position'' but the missions and decisions have something to do with ''progress'', I guess. So if you alter that value, lets say add 1, it should change missions and dialogues. But I really dont know what number would get you a position prior to futa decision.
Right now I have completed all the possiblities with her and my value shows 11. Lets say if you were to make it 8 or 9 this might put you into a position before you had these ''bed time'' talks with her.
But still I really dont know and am not sure about that. Please back up your saves before trying.
For my second playthrough I was experimenting, and I cheated to get talent points. I maxed out everything. But Bianca mission required me to improve my thievery skill. So I could not cuz its maxed. I just change her progress value with only adding 1, with this program and it worked.
