But that's the problem. For non-sissy path there's no more choice. MC just decides to sacrifice her to BBC by default. And since the gender change path relies exclusively on her it's now officially blocked.
Still, all of this could had been easily avoided if we were just allowed to play our old saves.
As it stands 60% of all people in the app and our choices on them get erased... And if you restart their paths you get a default sissy path and no option to add the wife.
I hate cascade quests where one path relies on another that relies on another that relies on another and so on...
Also what is the difference between "AWifesPhone.exe" and "AWifesPhone05.exe"?
Uhm I think you are confusing the paths.
If you don't add your wife nor yourself to the app and choose to go on the new sissy path. On this path you will not be able to make a choice on how to act on Julias branch. As I wrote before, most likely because the other choices (XY or Paul->Paula) don't make sense when you are being sissyfied.
If you don't add your wife nor yourself and choose the cuck path, you will get the choice on the Julia branch and go the XY route if desired.
Same if you add your wife, you can basically play as before.
Save game incompatability is quite normal for sandbox type games. Loading a save from an earlier version is always a risk because some variables might not be set to expected values, some might not even be defined. This can lead to unexpected behavior. Some people like to complain about sandboxes, but I prefer them to most of the VNs and KNs.
