I added some rivers in Palawan (Philippines), but they dont seem to be rendered on the standard osm map. It seems all rivers (even older ones, still visible at low zoom levels) are disappearing on the latest rendered tiles in Palawan (so it does not seem to be a "be patient" problem). Other islands are not affected, so I guess something must be wrong with the island. I cant find any problem though. Other styles (cycle map for instance) seem to render the rivers correctly. New highways also render correctly. Is there something special about waterway rendering?

Anybody has an explanation ? Where to get help?
