Hey, could always make it a feature. Urban planning and all that. A sign stating "Real Estate for Sale" would be nice though if the worldgen can detect it as empty. :P

That's actually an accurate representation of Gouldsboro, Maine. It's kinda scary.

@l29ah What's your setting for size of cities?

[l29ah]

4

That explains it. According to the code, with size of cities set to 4 or less, there is a fairly high chance to spawn such 1-tile "city".
We might need to increase the minimum size of cities to 2 to fix this issue.
