Ok, so we can exclude the multiple lines on top of each other. If I use the continue statement it draws the same lines as without continue, so that confirms it too. But why does this 'continue' solves the issue? If I exclude the following rule, # highway=* & highway!=proposed & area!=yes [0x07] it looks like it draws exactly the same highways, except that the routing doesnt break anymore.
Well in my map, they are indeed the same, and the problem exists too. For my map it's
0x05 road_class=1 road_speed=1 0x06 road_class=1 road_speed=1
and it breaks too. I think having identical routable lines on top of each other, is more likely to cause error, than different road_class and road_speed.
(P.S I'm just trying out Steves sr.patch from above - but map still rendering)
