I had this happen last week with a custom map, when I deleted a problem city (which also deleted the terrain). Importing the equivalent city tile from a copy didn't replace the terrain, so I moved the existing region (the one with the cities) into the Regions\Downloads folder and copied a new, blank' one into the Regions folder, and imported all of the existing cites EXCEPT the affected tile.
Hope one of these two methods will help you!
