Ninoss, I admit this is my first time to play this in a while. However, at some point something must have changed to make this game almost unplayable for me.
The girls are very eager to run from the lesson. There's no indication that one of them is stressed or anything, I'm not even doing anything to her, and she decides to run away. I know your actions affect others in the room, but at one point she's sitting quietly and learning, and the next second she's gone. Some visual indicator of an agitated/stressed state would be good, as the ones used in the past (like endurance) are not enough anymore.
What's even more horrible, however, is that a girl can run off on a game load. Come on, if I'm saving a game, I expect it to be in a stable state. I don't expect that state to change between the game loading and me getting control back. Please do get rid of that.
EDIT: plain v0.366, no mods of any kind.
