I will update the polygon data for USA as well.

There has been some renames in OSM, but I will rename them in Project-GC when importing, to make it easier for everyone. The only change I can see is that county Valdez-Cordova (AK) in Alaska will be split into two:
[*] Chugach (AK)
[*] Copper River (AK)

The final import will take at least one more week until it happens. Waiting on polygon data to be calculated. It's a 7-10 day job to calculate the polygon of USA against the coastline.

There are also these name changes, that are more of corrections. It must be some form of mistake on my part that they have a double suffix today.

[*] Carroll County (IL) (Illinois) -> Carroll County (IL)
[*] Carroll County (MD) (Maryland) -> Carroll County (MD)
[*] Lee County (IL) (Illinois) -> Lee County (IL)
[*] Morgan County (WV) (West Virginia) -> Morgan County (WV)
[*] Southeast Fairbanks (AK) (Alaska) -> Southeast Fairbanks (AK)
[*] Stephenson County (IL) (Illinois) -> Stephenson County (IL)
[*] Whiteside County (IL) (Illinois) -> Whiteside County (IL)
[*] Winnebago County (IL) (Illinois) -> Winnebago County (IL)

Importing the new polygons now, to get the name corrections in there. I will have to do another import in a week to get a proper polygon for the country itself, but that shouldn't affect anything but visuals on maps. And probably not even possible to see the difference anyway.
