Hi! I'm looking for a mod that disables the teen-elder household requirement when using CAS. I'm wanting to try a challenge where I play as a lone child, and I already have a mod that prevents the game from ending when there are no adults left in the household, but the inability to use CAS without running into the teen-elder requirement is preventing me from going forward with the challenge.
Does such a mod exist? And if so, where could I find it?

I don't know of any mods like that (and I've been searching for my own challenge) but what I did was creating a vampire sim in the child's household and putting them perpetually on Vampire Hibernation in a coffin. They don't wake up from that unless you manually make them and their needs don't go down, so you're essentially playing with only the child.
