Jarvan Bug

Please fix Jarvan's idiotic E+Q bug. Numerous times in my games I've tried to engage (with or without flash) with my standard/knock-up combo. My standard will land then my Q will shoot off in a random direction. Then what can I do? Auto-attack until I die and lose my team the game winning fight. I'm sick and tired of this shit and it's literally cost me several games. Fix it.
