Is there a certain percentage of chance to get that scene or should it always trigger when you follow the walkthrough? And does the time matter? I used your saves btw.Yeah that's the wrong scene, you need to get the scene where you knock on the door and Rachel invites you to have tea and you have to follow or stay.
I've don't it multiple and I got it each time.
I even got it when I had the incest patch installed, it was a bit more difficult to get the scene, but I still got it.
