Routing with Ireland osm file produces stranges results. I removed all errors found in the converted polish format file with mapedit but the result is still strange with Mapsource : - in many cases the pathfinding stops with an error, - the path defined does not respect any one way restriction on motor ways, - the diabolic pink line can vanish along a road and it can reappear few hundreds meters further, - the time computed for the route is totally wrong (it is like speed are minored by a factor between 8 and 12). In mapedit, pathfinding works well without any error on converted osm to polish format file. I did not find yet a clue in ... Any idea is welcome. What it is done with mkgmap is really a good work, thank you for this tool.
