shaco azir tower bug

I just had a game where if you are targeted by azir's tower as shaco and you q out, the red line will stay forever on shaco until the tower is gone even if you are out of the tower range. Not sure if the enemy could see me while in invisible but the udyr was walking as if he was trying to auto attack me but since i was still technically invisible he couldnt stun me because he couldnt auto attack.
