There are quite a few ways in the database which are passing by several times the same point. Such an example: http://www.openstreetmap.org/browse/way/191420773
There are lot of those in this area, but I've such seen a ways a bit everywhere in the map. It seems like it's pretty easy to do with Potlatch, and really hard to fix :-/
Anyway, is there a tool to fix such a way? Or maybe someone has a tip on how to fix them easily?
