i started playing with PathNode, i did not figure out how to move one around, os instead i just clear the path and redraw it when stuff resizes or pieces are moved
at least the rescaling and clearing seems to work fine on first glance but sometimes that exception throws and the whole jfx window goes funky
it could alos be a sideeffect of updating to 0.8.0-RC1 ofc and this is completely unrelated to paths
i also use some utf8 geometric symbols in strings now, could jfx have a issue with rendering those ?
