There is a new scene, but not from "asking Billy about his day with Janice" but you will have to repeat it in order to get the option to ask Rachel out to the beach during the mom swap.Please ask questions.
717. (Billy) After the school talk to Billy and offer him to "Swap moms for a day" ("Ask Billy about his day with Janice" must be done).
Is there a scene added to 717? In Ver0.36.
I saw that scene in the Ver0.35.
There's no new scene on 717?
I recommend ask for mom swap, go through the scene, ask Billy about his day with Janice, repeat the mom swap one more time and the option to go the beach should appear.
