Today I will update USA's polygon data with OSM data from 2020-04-04 (Y-M-D). From what I can see there are no changes. But since it's a big country I wanted to inform you anyway. In case you hear something, you know what it could be.

Here is the output of the compare script between live and a test import.
LIVE Country areas:  count=1  geom4326=10,318,021 km²  geom4326_landonly=94,852,516 km²
TEST Country areas:  count=1  geom4326=10,320,530 km²  geom4326_landonly=94,847,498 km²

LIVE Region areas:  count=51  geom4326=10,090,286 km²  geom4326_landonly=94,852,513 km²
TEST Region areas:  count=51  geom4326=10,092,795 km²  geom4326_landonly=94,847,495 km²

LIVE Counties areas:  count=3143  geom4326=9,711,791 km²  geom4326_landonly=93,612,574 km²
TEST Counties areas:  count=3143  geom4326=9,714,048 km²  geom4326_landonly=93,607,533 km²

There were four renamed counties in OSM, but I forced PGC to use the old ones to keep better backwards compatibility with existing challenge checkers.
