When using a world.icon_size smaller than the actual size of the turfs icon, I am unable to place turfs at the top and right edge of the map in the map editor.
icon_size = 18 /// I was actually using 18x11, but 18 does the same thing.
icon = 'turf.dmi' Just a basic 32x32 icon
icon_state = "green"
icon_state = "blue"
