There are a number of cities that are doubled in Baltimore county, Maryland. The 2nd copy of the cities appeared recently(ish). I’m guessing it is due to a change in the boundary designation in OpenSteetMap. Some of the cities double counted include Carney, Parkville, Perry Hall, Overlea, Rossville, White Marsh, and Hampton.
This does not seem ideal.
Thanks in advance for any replies and fixes.
