[GAMEPLAY] Sion Q and Ult bug

Everything was normal at first, but when I unlocked my Ult, I don't know why or what happened, I couldn't use my Q or my Ult. My W and E key were still working, as well as any other function that I used during the game (Except Q and R, of course). I was still hearing the little click that occurs when you use and ability, and clicking on either of the glitched moves wouldn't work as well (It did for E and W though). I didn't see any problem buying stuff in the shop or anything alike.
