Thanks, with the logging.properties from http://www.mkgmap.org.uk/pipermail/mkgmap-dev/2009q3/003993.html I got some warnings about roundabouts and fixed a few already. > > One more question: What about roundabouts that have been split because of > > bus route relations (bus routes would usually not circle the whole > > roundabout)?

I did not find the old discussion on a problematic roundabout, so I cannot check the data. I am just guessing that the problem could be that the roundabout segments were not tagged junction=roundabout (because some validator or renderer could have problems with roundabouts defined in multiple segments). That would be an error of the validator or renderer, of course. Best regards, Marko
