The SC technical schools are already included in the yellow star layer of both maps. Not sure if you have that layer unchecked or if I'm missing something
As I said in my first post in this thread, you only have the main campuses shown. But almost all of them have satellite campuses and those aren't shown on your map. For instance, besides the Beltline Campus of Midlands Technical College, there's also the Airport, Batesburg-Leesville, Fairfield, Fort Jackson, Harbison, and Northeast Campuses, each of which has their own focus area. (For instance, for the classes I'm currently taking, they'll all be at the Airport or Beltline campuses, and hopefully just the Airport campus, but if I were taking theatre classes, they'd all be at the Harbison campus where the theater is.)
