Have you still not unlocked the Katja stuff? I will tell you everything I did step by step and if it worked for me it has to work for you too, right?
Step 1 - As far as I could tell from my save testing it decides on the tick of midnight if the event will pop or not so just save/reloading before Morning Break at school won't make it pop, at least I never got it to, but I did get it to pop on reloading from the night before. So skip your morning routine for a day and just go to school and see if it happens, if not, reload the night before and try again.
The event is a conversation between Katja and a boy she doesn't want to go out with and her sister makes him go away with some dialogue I liked. After that she should be available to hang out with after school. Do that, play with the new events, since that might be needed to trigger the next part.
Step 2 - Get to the end of the next school day, save the game and click on Katja, keep reloading until an event at her house starts with her mother talking to somebody. I think that is access to all possible Katja content now. I assume just talking to her at home and stuff will unlock everything else.
Being drunk at the club just has a scene if you lean on the wall or dance by yourself where either Katja or Sonia will take you home but nothing happens from those events.
Whilst I have peoples attention has my Anya bugged? I can't talk to her about Roma, did I miss doing something this time that I haven't realised? I've seen them both outside, I've talked to her, I've drunk with them outside the community centre but no option to talk about Roma. She also doesn't invite me to the party, I can still go if I talk to her on the day but she never asks. Have I bugged this content somehow or did I hopefully forget to do something simple?
