On top of a map I have traced a path along a route that the characters should be taking. My players are reporting that the path I've drawn is significantly to the right of where it should be (meaning they will be swimming with the fishies)
the color selector is a color changer, not a selector. In other words, you have to draw in black all the time, then select what you've drawn and THEN change the color to what you want it to be.
