Sorry to take so long to get back to you. Maybe it's my cache file but if you haven't found it already, here's what I was talking about.
Go to a field town and from directly overhead you'll see the buildings, radio tower and even the gun emplacements are shifted 50 to 100 feet north north east.
The offset location of the gun emplacements and radio tower compared to the gray "paving" confirms it for me.
I first noticed on the Ozkansas map but it's also in the current map.
