So, two things.
1: When am I supposed to have Anne seduce Adrien? I had managed to get the decoder and hacking device at three hearts or so, but I never could tell Anna about it. I suppose I had to do it earlier, but when is the right time?
2: You can invite Josef to join you and River it said in a user guide, but I can't figure out how to do so. Any advice, or did I do something wrong?

I'm having the same bug with the hacking info, and I think it may be due to me selecting the "Adrien Leave Route" when speaking with Adrien about paying for him to fuck off to Japan
