 * I just pushed an update with a lot of missing new field default settings. This
   is the only thing that was clear to me that I could fix based on these logs. 
   Let me know if the latest version cuts down on these errors for you or if there’s
   something more specific I can try and help you with.
 * Thanks,
    Andy
