[mkgmap-dev] River flooding with r1955

Hi, While geocaching on Saturday, I noticed an area of the map that was flooded. It seems the following relation is the culprit: http://www.openstreetmap.org/browse/relation/169902 It renders correctly in the openstreetmap, but the mkgmap generated map floods a large area with water: http://www.openstreetmap.org/?lat=36.13856&lon=-78.9059&zoom=15 Any thoughts?
