I am on level 19 of the game, but I am having a problem constructing a house. I bought and built a house and added a Sim, but they didn't add to the overall count of people to the town, and the house won't complete construction. Now, everytime I try to complete construction of the house or access the Sim I created, I have to make a new Sim. I have about six Sims in one house and I can't get them to work or interact with anyone else in the town. I've shut down the game and completely turned off my phone, but this hasn't fixed the problem.
