[mkgmap-dev] generate-sea:polygons broken between mkgmap r2160 and r2168

Hi list, Just upgrading mkgmap to keep up to date and I find that --generate-sea:polygons has been broken somewhere between mkgmap-r2160 (which works) and mkgmap-r2168 (which doesn't). Screenshot 1: created with mkgmap-r2160 http://cferrero.net/maps/img/r2160.png Screenshot 2: created with mkgmap-r2168 http://cferrero.net/maps/img/r2168.png As you can see, by r2168 the sea is no longer being drawn (the blue bits that remain are actually mangrove or wetland polygons). I used the same command for screenshots 1 & 2: --generate-sea:polygons,extend-sea-sectors,land-tag=natural=background Can someone see what bug was introduced? -- Charlie
