I had two girls, Saphesse (I think) and Fate. Both were sent upon turning 14 . I naively thought the kids would visit home weekly, bimonthly, or every quarter... nope, they don't.
The one I chose to randomly inherit the house was Saphesse (if that was her name, I disliked her so I don't really remember it). In a nutshell she made 500 coins a day at her peak. Before dropping down to 200. I don't know if it was a glitch or if anyone has had similar experiences.
She was also a meanie of a mother! Horrible, horrible woman.
