[OSM-newbies] Odd Potlatch 2 rendering

[Kenneth Pardue]

Can someone explain why Potlatch2 renders this area strangely, but it is rendered correctly in Mapnik and Potlatch 1.4?

It's almost as if Potlatch2 doesn't recognize the other end of the multipolygon so it's drawing its own shading, but I believe the entire river segment has proper relations set.

Is this a bug in Potlatch 2?
