Yesterday I started seeing complete carbon copies of the sim in the household I'm currently playing. Same clothes and hair and same names. these duplicates are even asking to come over to hangout. So...
Ideas
Are you using mods/cc ? Do you have those Sims saved to your library or are they not Sims you created ?
I don't use mods or CC. These are sims I made myself maybe a week or 2 ago. Is there a way I can delete this duplicate family. It is all the ages since yesterday I saw the duplicate of Young Adult.
