Areas tagged with the tag waterway = rivebank http://wiki.openstreetmap.org/index.php/Tag:waterway%3Driverbank do not seem to be rendering in Mapnik. Compare the Mapnik and Tiles at home layers at http://www.informationfreeway.org/?lat=33.46&lon=44.314&zoom=12&layers=0000F0B0F I wonder if this could be fixed fairly soon. Regards Davids Groom
