When the lakes were tagged with natural=coastline they would have been
rendered via the coastline polygon shapefiles. I last updated the
shapefiles used by the Mapnik layer on April 8th. If these lakes had the
coastline tags before on this date then they will still render as 'sea'
until I next import the shapefiles.
I typically update the shapefiles used by mapnik every week or two
depending on whether I notice any significant differences in the
coastline checker.
