I am not sure about that, but it may be a maximum counter issue. I got the Liz and Faye on the roof part 2 scene before doing the filmed class demo ending Chapter 1. It gave me the Horniness point, but then only gave me 2 for demo, presumably because the chapter 1 max was set to 9. Then when I got that event again the next weekend, it gave me another point, but counted the one blocked from chapter 1, so I had 11. Presumably, it will not allow me to get 32 Horniness because of it, but maybe. It would be odd if that actually prevented the trigger for the scene (like, "Horn < 31" or something) but you never know.
