Ok, I see. It seems more like a bug with something stacking somewhere it shouldn't.Thanks for both the change and the explanation.
Actually, the seed is not saved with RenPy, so reloading the save does change outcomes. What you are talking about is rolling back an action. But that's not what I was talking about.
You are in a lesson, with all three girls in class and nothing happening (the game waits for your action). You save. You reload that save and - before you can do anything - two of those girls decide to flee complaining on their nakedness.
You reload the same save again. All three of them flee.
Again. One flees.
Again. You ask one of the girls how she feels, and two other flee.
Again. None flees, and you can do the action you planned to do in the first place.
I can provide you with a save to show you what I'm talking about if you have trouble reproducing it.
I've never saved during exam tho-, I always save in a "safe" RenPy spot so to say. I'll try to reproduce the bug
