When are the coastlines rerendered in Mapnik? I retraced the coastline around Lidköping 10 days ago, and the beach I marked [1] turned up minutes later, but the coastline still looks as before, which I find rather strange. Are costlines/oceans on a separate layer from the other visual stuff on Mapnik? [1] http://osm.org/go/0YcnfIA5 regards Konrad Skeri
