Could you try correcting some parts of the "Suzuki Matsui" story?
I've tried this several times in the latest versions (including the latest one (0.968)). I can meet her twice at work, then invite her home until that part of her story ends. After that, I have no further instructions on what to do with her in my journal. I then find her at the mall where she keeps gambling and losing, telling her to call me back later, but it never happens.
If I try to call her after that, she either doesn't answer or tells me to call back later because she's working, which leads nowhere.
(I met her at the mall before I could ask her for help with the Ayano Festival, if that helps you resolve the issue.)
The "Meiko Tsucasa" story also has problems. If you choose to bribe her and then invite her to the Occult Club, you won't see her member image when you give her a task. (The whole "Further Bribing" part you've seen so far is very unclear, as is sometimes the case with many main character stories. Could you give us a walkthrough for those stories? It would be a good way to know when something is wrong and to better understand what's new.)
Oh, before I forget, it's still impossible to choose piercings or tattoos for our character.
