Hello, I have been working with some polygon data, and found a weird overlap with some polygons. Some small islands have the same polygon as the ADM2 they're contained in, some examples are here:
Nicollet Island same size as Hennepin (ADM2 containing Minneapolis)
Sauvie Island same size as Multnomah (ADM2 containing Portland)
Northerly Island same size as Cook (ADM2 containing Chicago)
I checked it on google maps, and they seem to verify that they're not supposed to have this polygon.
This is only a problem that's been seen in the US. Not sure if this is the correct spot for this to go to any relevant party, maybe others have noticed the same problem.
