kid living alone?

I’ve had this happen to me. A couple times. I was going through my “ other households” to delete some of my over populated townies and saw him. He was living in the Johnny Zest trailer. I was surprised he was living alone and kept him to check out later. I was playing my wealthy household when I noticed him walking past the house. I just shift clicked on him and added him to my household and had the parents adopt him as his caretaker. The second time I saw it I just moved the child in with another townie household. Both times the child was male and had 20,000 dollars in their household funds. I have mods so I thought it was because of them.
