Cool App, But Keeps Shutting Down

My kids really like this app (truth is, so do I), but it keeps shutting down. Theres a dwelling on the right side of the main island that looks like a few store front (maybe); every time we try to build it, the app shuts itself down. Its really annoying, so thats the only reason I didnt give it more stars.
