After reading this thread, I now have elders who are master parents! This was sooo easy, I thought it was too good to be true...I was kind of right. Right now every single one of my female villagers who are of child bearing age have babies, all at the same time! And my female master parents have chosen their favorite younger males to dominate! (They are either in the love shack or waiting for someone)
As hilarious as this may be, know that if you choose to make elders through master parenting be prepared to micromanage more than you already do!
