I've been using this method to backup my game for a few weeks without problem, then today I noticed that the 'Mobile documents' folder for IB2 is 2 days old, whereas before it would update within about 10mins of playing the game. I'm using iOS6 on my iPad (3) and mountain lion on my mac. Any ideas why the 'mobile documents' folder is not updating? as now I cannot make a back up of my files with this method. Any help would be appreciated.
