I guess you could say it's a...The sister gets created right after you pick your own character stats/image. Did that process complete properly?
I've played pretty much every update of this game since launch (absolutely love your work) - and not once have I cared about how the guys look, so I usually just delete the dude image folders and have the guys all look like clones with face masks on lol.
I actually completely forget the dudes are meant to have images.
Turns out this was breaking the new function of choosing your sister's image, as it was never prompting me to choose what my own guy looks like (which was the preceding step to choosing what the sister looks like).
So I added a dude image pack and now it's spawning the sister.
Again, love your work. Definitely a novel and harmless way to use AI art, and probably my favourite game since Lab Rats 2.
If I could make one single suggestion it would relate to the above and be a 'straight/bi/gay' toggle which would simply change all male images to be the same 'shadow dude' looking image, or gay mode would change all female characters to be a shadow lady (like an anonymous looking person). Bi would show all images.
Obviously just a suggestion - might be a stupid one idk. Game is great regardless. I just feel that most people would be playing to manage the gender that they're interested in sexually, but that might just be me.
Have a great day man.
