[EBN] Premade Fairy Sims aren't actually fairies in CAS (existing Saves)

Same for me. Brand new game, is fine no mods. Only the child shows as a fairy. Every other save sim is a human. In every household. 

Edit: although if you go into the houses and select "change sim" on a mirror they will get their fairy forms and the game will recognise them as faries again.
