Interestingly, yes, thanks for that, I tried to save and load just before enters Ingnetta's brothel room, and it worked, but a little bit funny because it replays the scene with one of her patrons (which I already did before), then after I end the day by back to academy, as soon as I enter, the scene advances smoothly, and to another attempt I try to re-enter the next day it seems nothing troubles me, until I unlocks all of her available scenes.
