Not sure if anyone has spotted this before, as I have not been keeping a close eye on the mailing list lately.
 
I had the following defined in my style file; to show thinner lines for primary highways at different zoom levels:
 
highway=primary [0x1b road_class=2 road_speed=1 level 3-4 continue]
highway=primary [0x03 road_class=2 road_speed=1 level 2]
 
This seems to have broken routing in Mapsource and on the device. I removed the first line and changed the level on the second to 3 and it worked fine (I assume 4 would have worked fine as well).
 
Is there a restriction on doing this type of thing regarding routing?
