Vanessa isn't broken, that's just where her content stops. Same with Kelsey. I keep trying to find time to write, but this last year has been a shit show, and since the mod characters were a hobby, that got put pretty far on the back burner.
Naomi on the other hand, should be finished aside from having no repeat scenes. So that's odd. After that message if I remember right you should meet her on the evening at the park? It's been a while. I'd suggest either here or in the Discord sharing your save so someone could check out if something's funky. I know there was a release where Noodle uploaded the wrong js for her and borked up some trust values, but I know there was a fix put out that would have fixed that issue if you ran into it.
