Sims keep changing after updates!!
After I update my game to the latest patch, when I go into my library or go to play one of my game saves, all my sims look different! Every sims appearance has changed, and they no longer look right....

Do you have any mods or CC (custom content)? Try taking that out.
See this for more information: [PLEASE READ] Usage of Mods and Custom Content
If you used CC to make the sims, make sure the game did not disable it in settings when it updated, and make sure it is all compatible with the patch.
