[GAMEPLAY] Vel'Koz Ult Bug (Uncontrollable double-duration laser)

During a game, I, as Vel'Koz, flash and use my w and e, then ult. For some reason I cannot turn the laser after one second through the channeling. Then, I'm not sure if I press r to cancel the ult, but somehow I ult again for the full duration of the laser, although I can't remember if I could direct this one.

I think I might have accidentally pressed a button during the ult. Really, that's all I can say, there isn't really something definite that I can express which could duplicate the bug.

is broken. I'm not sure how, but if somehow people find out how to extend the ult duration, this could be a gamebreaking thing.
