I think i found a bug with Lee Sin.

I was playing ranked with Lee Sin and this Riven got very low. I approached a wall on the top side of the map to to ward jump over it then q her for the kill. I used my trinket ward to do the ward jump. After I did the ward jump, it sent me back over the wall where I came from, and my w was on cool down. I used my q in rapid succession with his w. Here are the items I had at this point in the game: Stalkers Blade, Boots of Speed, A ward, and a Health Pot. I'm sorry i can not provide a screenshot or video, but it was at 9:30 in my most recent Lee Sin game, is that is of any help. Thanks.

Edit: I just got some pictures, sorry about the terrible quality.
