The map data is updated continuously from minutely diffs, but the map
tiles weren't expired automatically, so you might well have been seeing
old data. I have added a daily expiry now.

The overlay with the red multipolygon outlines is updated and the tiles
expired daily.

If you still see discrepancies, check the OSM Inspector
http://tools.geofabrik.de/osmi/?view=areas . If it reports any problems,
fix those. Then, if there are still problems, email me or open an issue
at https://github.com/osmlab/fixing-polygons-in-osm/issues with specific
information about the OSM objects that are rendered incorrectly.
