The way i understood it the name part wasn't the glitch, when she changed the name though it changed both names and not just the one she wanted changed.
Exactly. I know that people can be named after other people, and that the random name generator may come up with the same name more than once. If Niece Gaga wants to be called Gina (or whatever), Aunt Gaga shouldn't have to change her name to Gina too.

Just wanted to throw it out there as a possible issue for future updates.
