OK.

OK.

Testing with mapsource on tiled maps of the UK and the Netherlands, I
can route across multiple tiles (in one case, I counted 7 tiles).

However, mapsource often gives up when trying to route long distances
(especially with the UK map compared to the NL) so I wonder if there's
some complexity contstraint that we're not adhering to.

But to answer your original question, multiple tiles can be routed
across.

Cheers,

Mark
