The administrative boundary between Georgia and Alabama is shown as going down the center of the Chattahoochee River from Early County southward.  This is incorrect, as the boundary actually follows the western bank of the Chattahoochee River.  That may seem like nitpicking, but it's actually of some importance as there have been lawsuits between Georgia and Alabama (and Florida) over the water rights to this river.

Thing is, though, I don't know how to change this on the map.  The Administrative Boundary needs to be somehow separated from the river and relocated to the riverbank.
