After seeing your post, I decided to test some more, and you're correct that it has nothing to do with karma. My testing has indicated that I have to go into Lucy's room between 23:00 and 1:00 in order to trigger the Lucy event. All the times I tested before or after that window results in just Lucy, Lauren, Sarah watching TV.Send me your save, Im interested in checking this. Cause Karma doesnt stop/prevent any scenes or related to anything triggering in the game. It is just there for no reason. If you could, send me your save before you change it for the Lucy event
I'm not sure if this behavior is intended or if I had inadvertently triggered a bug prior to this, so I've attached the save for your reference.
