Well, I like some other people have noted that Basecamp 4.2.1 doesn't autoroute very well. I tried through many examples, and what I found out was that intertile routing seems to be the major problem. As soon as the route leaves one tile more than two times - to go back into it, seems to crash the routing - if it is the preferred way. Anyone else finds another solution?
