Re: Worldwide routable Garmin maps: URL REMOVED

In the past I have downloaded tiles, combined them with with Mkgmap using a script file. Recently I downloaded a group of tiles and the combiner failed, complaining "

Have there been changes to anything in the data structures that would cause this error string? I have not changed either mkgmap or java in well over the year since i used it last.
