Re: 1 sim won't age up
@92cf2b7580a24fb2 Yeah, AFAIK, she's immortal. She used to be the Tutorial Sim.
She has a trait you need to remove
Try typing this in the cheat console to remove the trait
traits.remove_trait Trait_SpecialNPC_isFTUERoommate
(hope there's not typos and that it's the correct trait)
After that she should be able to age.
