Summary0000330: Definition Merge=Append causes infinite list duplication and then game hang if the modded list is empty

If you try to create a definition in a mod that's set to append to an existing one, but the section of the definition that contains a list is omitted, the source list is duplicated infinitely, eventually causing an OutOfMemoryException.

Steps To Reproduce

Create a new PlanetMapDefinition, copying the data from the vanilla MapDefinition.sbc
Set Merge=Append in the definition
Omit either RegionView or KingdomView entirely
Load the mod

Additional Information

Additionally, the game will hang with a black background after you click the button to dismiss the error popup.
