Automapping doesn't work with the edge of the map

[StoryTeller]

I just try to make a simple automapping. It almost work well until I see the edge of the map.
Look like the map doesn’t treat the tiles on the edge as “nonempty tile”.
How can I fix that?

Take a look at the various Map Properties for matching outside the map. You’d probably want OverflowBorder.
