[GAMEPLAY] Problem with Vi's Q Since 6.5 Patch

It's not easy to reproduce but it's happened to me 3 times when charging Vi's Q towards the bottom of the screen. When charging aim arrow grows past the bottom of the game area and the mouse cursor drifts over the menu items on the bottom, I was unable complete her Q with another mouse click. Even after correcting the camera so that the mouse cursor was on the game map, a mouse click to send her charging forward does not work. She's basically stuck in place until the Q charge times out.
