Running Chrome on a mac, on the map or token layer of my map, I can draw elipses, rectangles, and freehand squiggly shapes, but the pen function won't draw any color and won't activate at all. It's not drawing invisible lines, it's just doing nothing. I tried changing my player color and tried re-launching the game, and tried changing the colors multiple times and the line sizes from medium to very large, etc. I can't get the pen to draw!
