Just for clarity, the patch is INCLUDED IN THE GAME AND OFFICIAL, regardless of what some users who can't read might say on here.
The incest patch is just a flag that tells the game "Oh, this file exists, load the incest relationships"
I've explained that multiple times but some users cannot read. They keep claiming I'm calling Madeleine the MC's biological mother, when I've never said that. Like in this post where TheDevian says "There is no way to make that work, unless you change the entire story background." and of course I'm a dick when I've explained 4 or 5 times and people still misrepresent and put words in my mouth -_-
So, with the OFFICIAL patch, from the MC point of view:
His father is his father
Madeleine is his stepmother
The 3 girls are his step-sisters and Madeleine's biological daughters, not some girls she tutors.
That's how it is and that's how the dev intended it. (Whether it started like this and changed due to Patreon or it was always a hidden option I don't know)
Also, TheDevian, judging by your posts you seem to be on the dev team or talk to them, if you don't condone the use of incest patch all you have to do is remove the "Assets/gamedata/mapping/old/" files and the code I show in the "Patreon censorship" spoiler which you glossed over in your reply. That way any incest patch made won't be included in the game and it'll be ACTUALLY UNOFFICIAL.
How do you figure step sisters? If the MC's father also fathered the girls that would make then his half sisters.
