[mkgmap-dev] Changing from RESOLUTION RANGE to single RESOLUTION causes compile error in r3665

Default line style has this: highway=trunk & ( network=e-road | int_ref=* ) [0x02 resolution 15-17 continue] I wanted to only show this on RESOLUTION 17, so I changed it to this: highway=trunk & ( network=e-road | int_ref=* ) [0x02 resolution 17 continue] Now when I compile using mkgmap -r3665 I get this error: Warning: routable type 0x02 is used for non-routable line with level 0. This may break routing. Style file lines, line 165. How does changing the Resolution Range to a single Resolution cause this error? Greg
