I'm aware of Katarina. The issue is that reloading a save has made doing that impossible because even though I've interacted with her as I should plenty of times in Mario's office, even after waiting two weeks, she still acts as if I haven't done anything to her (indeed, Emma is in the Terrace now at all times and doesn't even show up in the Sauna anymore). Even when Katarina did show up in the Terrace, she didn't have the progression option.
