Hi, I forgot to report that changing the order of nodes did not change the result in MapSource, so this is a different problem.

The case is really strange. When I build a DACH map - the routing is OK When I try a data extract from JOSM with just this part of Kaufbeuren - the routing is OK Anytime I build a BAYERN map - the routing is BAD. So only the tile generated by splitter for the BAYERN map provokes the bad routing. I suppose that the tile containing Kaufbeuren generated for the DACH map does not start at the same coordinates as the one generated for BAYERN. This is the only difference I can imagine. I uploaded the splitter-generated area information in the hope it might be helpful. http://files.mkgmap.org.uk/download/167/bayern_areas.tgz The tile in question is 65020003.
