Game autonomously changes last name of played married Sims
I created a family where the spouses had different last names. After playing with the family, going to manage worlds, then going back to playing the family, the last name of the female Sim had changed to the masculine frame non-binary Sim's last name. The game shouldn't autonomously change female Sims names to default masculine last name. I also don't want my game changing played Sims names at all. This should be left to the player.
While some people might not mind this, it should be more of a 50/50 split where last names of NPCs do change between masculine and feminine frame Sims. For instance, Nancy Landgrabb would never change her last name as has happened several times in games where she's remarried after divorcing/Geoffrey dying.
At the minimum, last names of played Sims shouldn't autonomously change without player input.
