I don't know if this has happened to anyone else, but it did to me. I had a family with two kids and when the first grew up, I moved her out and played with her as the active household. An in-game week or so later, I saw that the parents had another child. So then, I wanted to play those two kids for a while and leave the firstborn on her own. When I changed active households to the parents, the kids weren't living there! I had to search around town to find out where they were. They were living with a complete stranger! This lady was not related to anyone, nor was she a friend of anyone in the family. This lady was acquaintances with the kids (I assume from living with them) and didn't even know the parents!
Any theories on this? Has this happened to anyone else? It was in Barnacle Bay and I'm wondering if this is some kind of freak occurrence.
