OR... if you're going to use automapping (because it is a good shortcut to get items mapped quickly), please, please PLEASE go back and edit what was mapped. Look for dynamic properties, close the application and re-open it to see if the objects STAY mapped, adjust properties, property values, etc., to be more robust. And for goodness sack, clean up your Aliases... no more
