Perhaps something is being reference in memory or cache incorrectly. Try to "force close" the Lost Islands app (by double clicking the Home button and then sliding the app up). Then try a hard reboot as this should clear the cache. To do that, press and hold the Sleep/Wake button and the Home button at the same time for at least ten seconds, until the Apple logo appears. It will restart the device, then you can try restarting the app. I hope that helps.
