Full Metal Rammus

I just bought the Full Metal Rammus Skin and noticed quickly , that there is a graphicbug. If you use his W, activate his Q and attack with your Q ... then you get the Colors of his W all over the Map for a short Frame. It's really fast, but still annoying as hell, can't make a screenshot of it because screenshotting one Frame is pretty hard. If you don't believe me, just try it out, doesn't happen everytime, but very often. Hopefully it will be fixed soon.
