Sims 3. Some of my Sims wont go outside of home lot?

If they won't leave, it's probably because the car belongs to just that sim

Ok do you have foundation at your house? If so you WILL need stairs leading up to your front door with flooring in between, not directly in front of the door cuz the path will be blocked. That could have been why there was a slash through the footsteps. It also could have been that ur second sim, who made it into the house, blocked the path of ur original sim. or To fix this simply bring up your cell phone and select the move option. Select everyone in your family, unless you wish to leave them behind. Sell your furniture so you'll have more money to fall back on ( you'll get everything you had back again ) and move into the opposite starter house you had the option of moving into at the begging of the game. Once you are there simply repeat these steps above and buy back your old house with the furniture in it. you will be able to play the game as if nothing happened.
