Ok, well, whenever I try to click on a house or a baby crib to put a person in there, it says, " a sims is already being added to the town. You must wait for them to finish before you add another." Yeah, the only problem is, nobody is being added! All of the cribs are black and white with the + and the picture of a person, and all the houses that are empty say that too. I even tryed deleting all the cribs, then buying them again, and it still won't work. What should I do????
