BUG REPORT GAMEPLAY Janna´s Q is bugged at quick cast

When you are escaping with janna and you turn rapidly to throw to the enemy a Q the ability goes crazy (only at quick cast). You lose the capacity of insta throw it pressing Q again because the game doesnt recognize that you used the skill but the tornado is casted and only after 1-2 seconds the game allow you to press Q again. The bug doest occur all time and you have to do it very fast.
