I wanted to add to bugs I've encountered in this version, and keep it in one thread.
I went for Wey first and when talking to him, found I could speed through his talking bar by clicking the green talk button that shows a little under the speech bubble. This makes the progress go significantly fast. This may be what broke everything. I finished his story, but every time I go to talk to him, it says I unlocked Wey. However, Wey is very much not unlocked. I can't invite him to my room.
I moved on to Da Thach but progressed him like normal. However, the same situation is happening: You unlocked a new Guest: Da Thach. Narrator: But he wasn't unlocked.
I've exited the game, tried changing outfits, tried grinding, hoping this may "reset" it, but it doesn't. So I don't know if the initial ubertalk messed it up, or if there is a bug where they won't unlock properly.
