[GAMEPLAY] Hugely impactful veigar bug

This just happened to me in a game of solo queue. Veigar laid down his stungate, and as soon as he walked into a brush (Which was control-warded), it went invisible. I thought it didn't cast or something so I tried to walk away, but then I ran into the invisible stungate. Excuse my garbage filming skills, but there's a clip of it happening in realtime and then in half-time. Pretty frustrating bug, and possibly very impactful if abused. In this specific instance, I had flash up but decided not to use it since the stungate disappeared, causing me to die.
