I noticed that during episode 7 when you normally have a chance to visit different places and talk to the crew that the only option that shows up is to return to the room. I am not sure if this is a bug (it feels like it) or somewhere I needed to choose a certain option to unlock them, but I'm missing those 3 chunks of dialog after talking to Ayame.
I'm on PC and I haven't had an opportunity to see if it happens on other routes, I am currently with Damon.
