might be a problem with my version. I downloaded v1.1.6 (Free Edition, Uncensored) for mac. I think I did everything right with Rachel but I never got the chance to get her. I didn't see any choices to get Bella.
But the main issue is that I have Liza, Adriana, and Susan (and Riley), and on the plane to the island Max is wondering how he'll explain the poly situation to them once they get there. Well, when we get there he talks like he explained the situation on the plane and he is thankful that they are speaking to each now. So I think maybe something went wrong somewhere.
