This was weird. With the last version I downloaded (says 1.11.1b) I had this bug(?).
The scene with
Lily and Leona in the bedroom abruptly cuts to a scene with
all the four of the founders
And a couple of renders after chosing one of them it ends abruptly again and it goes to the next day.
The game just made a spoiler for me
I closed the game and I loaded a save where you make the choice in the
founders scene, but it loaded the correct part of the initial scene and goes as it should until the point where it seems to end. Then it goes back to an earlier scene and I get what it looks like an alternative version with no
threesome option at all, I guess from a route without a relationship with Lily.
I closed the game, opened again, loaded the save and goes back to the wrong scene once again. But with some changes... I'm giving up for today.
I used scrappymod when I thought the game version was 1.10.1d but after I made a save I saw it was 1.11.1b, so maybe that's the problem. IDK. I removed the mod and still get the same problems.
