New Yasuo bug

Didnt have the game recorded...

I was in a game as Yasuo vs a Teemo top, my jg was Rek. Whenever Rek would gank i would charge q until i had tornado, then rek would knockup the teemo and id ult (without throwing my q). As soon as i finish animation i tried to q to lockdown the teemo, but the tornado disappeard, as in no tornado, no knockup. As well as that, after the ult animation and the disappearing q, i still had the indicator for the tornado around me until i Q'ed again (i later ulted off of a knockup from rek and didnt shoot my q even though it was charged, indicator stayed even after i let the q charge wear off ). This happened maybe 2 or 3 times during the game when id ult off of rek. Hopefully this gets fixed so that it doesnt happen during a teamfight and it doesnt throw off a yasuo in the teamfight.
