In my last game a Mob from the wildlands destroyed a city of mine. To my surprise, I could not resettle the land (i.e. no fertile ground left behind).
When I settled the town originally I owned a town to the NW but nothing else. When the town was destroyed I had captured an AI city nearby to the south. Are there different rules for city proximity to your own towns vs. an enemy's town?
Should the land have returned to it's previous fertile state? (bug?)
