Looked at your gallery, yeah you're missing Scarlett's scenes, Tomoe/Lars/Sky's later scenes, and one of Jazmin's, I believe final stage, non-penetration events, which you would need, I think, to get her last event. Have you got the other naked scenes with her yet? One where you eat her out, another where you take her top off on the couch, etc? If not, and everything on her list with the final stage is checked off with no changes/scenes after visiting her at every opportunity, then you might have a bug. Painstaking as it might be you may have to restart and just try prioritizing her and seeing how it goes-she's how you unlock Scar, Torres and Tomoe and crew's later scenes.
As for Scar, do you remember if you talked to Jaz about her giving you lessons yet, or did that not happen either? After that talk and a subsequent automatic meeting with her/Jaz in the next few days she's there, or should be, every Mon, Wed and Fri in the livingroom at noon. Advance everyone else-you hear about her(literally) during breakfast with one of the girls/Jaiden, can't remember who though, might even be automatic. And it goes without saying, if you haven't, be on the lookout for the ? in the living room. Either way if you haven't even talked about her becoming your tutor and everyone else is progressed to the final stage then you definitely have an issue/bug and you should restart to be sure.
Lmk if all that falls through and I'll do another speed-run myself to find out.
Are you sure you've finished all Jill's content? Including the short sex sex scene on the butterfly press? They(Sap/Gaz) should both appear before her 2nd shower scene, they did for me anyway. Did you get Sapphire's scene? I believe they both show up as ?'s in the living room between Jill's 1st scene and her 2nd. Check on all that and if it fails post a pic of your gallery/Jill's checklist and I'll see what I can do
Edit: And for both of you not every animation/event will appear in the gallery and you need most/all of them for certain scenes, be mindful of that as well.
