Hi Gerd & Carlos I've found the problem and attach a patch which reduces the Subdivision line limit to 254.
Subdivisions/areas have a set of limits, one of which was <= 255 lines. These lines can be of any type including roads. When --route, a reference to each line/road part is created, but these are numbered from 1, so the 255th line in a SubDivision is numbered 256 as a road segment and this can't be represented as a byte in the NET structures. It looks like this problem has always been there, but is most likely to manifest itself in areas with mostly roads. Ticker
