Programming error

Solid app, very good for quick study breaks. But just a heads up to the programmers, seems that you can get the computer to a point and force it to freeze if there is no double jump available. And you cant hit undo because its not your turn, so youre forced to quit and restart. This just happened to me, all kings and backed their kings into a corner. There is a single jump available but the computer wont take it. There was a single jump available a few turns before and the king didnt take it. Only doubles. Hope this helps the code.
