Hi Valentin, many thanks. I've just committed version r4391 which uses the older version of SeaGenerator. In my tests that worked fine with your areas.list. I test this with a trick: I split an empty osm file with your areas.list. This allows to compute all tiles within 2 minutes and the map just contains the sea data. Will continue tomorrow.
