[AA] Occult role filled with human occults in Custom Venues/Getaways

I could opend the "ghost" Sim in CAS and there he is not a ghost at all, after canceling out I was treeted with a infinity loading screen. 

My guess is for a custom venue, if there are not enough ghosts with the right criteria, the game just lables Npcs as ghosts and let them act as such. But this is just a guess.
