cant find sims household anywhere

@rpan23 Did you make a new save game by accident ?

If you click on New from the main menu, that will create a separate save. Can you click on load to see if you have a save game there with your old household ?

To add a new household to an existing save you need to do that from within the save. When you don't select a household on the main map screen, you get the option to create a new family in the lower right corner of the screen.
