So if I understand correctly you got someone's save in the right place, but when you load it in game it doesn't work? Well I am no expert, but 2 possibilities I see here are 1) Save was made with some kind of mods/edits so you can't use it on original game, 2) There seems to be some issues with saves in this update and this save you got might not work for everyone. Other than that I have no idea.
Umm guys... If your old saves don't work and you don't want to start from fresh try to load older saves... I loaded save with the choice for MC if he wants to be home when Brandon visits or he wants to pretend to not be home and my game worked fine. This is why making multiple saves at different parts/versions in the game is important. I usually try to have at least saves from past 2 versions of the game so if something was edited in previous version that breaks saves I just load save from pre-previous version and hope it works and doesn't force me to start fresh.
By the way update was decent for me, but this comes from a kinky pervert so I'm not sure if it felt nice for more vanilla players. Seems next update will be plot related and might have more hubby/wifey time so you guys will probably be trated well then, stay strong
What I would have liked to hear in this update was wifey and Brandon agreeing to make this a somewhat regular thing, something along the lines of "These "workouts" are so good we gonna have to make this a routine" or "Damn we should do this every time your husband is not home", provided you make the rights choices to like this sort of thing of course.
And last but not least, with all my blood from brain into my cock, I did fantasize about a moment where condom would break and they kept going or wifey would just straight up interrupt Brandon putting on condom for second round. I think that would be really hot, but I also understand that it might be seen as too forced/fast/out of the ordinary for this specific couple and story. Just my thoughts, peace
