I don't think there's anything that explicitly mentions Nea in the progress tracker, but she may be lumped into the overall Pool Party thing. Which makes it interesting because of other people who might be there, or that Nea would both need to be there and not be there depending on what path the player is now on. So maybe she's just not there at all as then it's only one set of renders for Luxee to do. Or maybe having to make versions where she was there but also ones where she was absent is what took up a lot of time for him. Story wise, I could see Nea not want to show up in a swimsuit, especially if some of the girls that bullied her are there.
