Well, at least with this update, the "diplomat route" is completely dead. I played from one of those saves out of curiosity and it was a disaster! My MC was with Tracy, Emma, Maude and Karla (alpha), only not Sunny and had good confidence. It went well at first, but suddenly without any warning there were only beta scenes for all girls coming, even those my MC was on total alpha path. There is something really wrong when a single not alpha path destroys all others.
I have to say it is sad, how this game has developed.
