Out of the blue the schoolbus and the carpool for my sims just parked in front of the family's house and neither vehicle has moved from in front of the house since then. When it is time for the kid to go to school or the adult to go to work, I click on the right vehicle and select "go to school" or "go to work." It lets me select the option but then the command disappears. How do I fix this? I am running sims on a macbook, if that is relevant to the problem.
