Not sure what Chris is referring to there.

I am aware of 2 issues related to inter-tile routing:

1 - the inability of mapsource to route across more than 1 tile
boundary.

2 - the problem where a route needs to go from one tile to another and
then back to the original tile (this could be related to problem 1).
