Lee Sin Q bug

So sometimes if you re-cast your Q as Lee Sin your character freaks out and you either stay at the spot you are when you re-cast it or you end up somewhere else random. I've had this happen when I had my Q on the big razor beak/raptor and I ended up in the wall after re-casting Q. This also happened to me when I Q'd an enemy near the Blue buff, to the right of midlane, I Q'd an enemy and then re-cast it and my character went backwards into the wall of Blue buff and no I did not get shot away by an enemy.
