[GAMEPLAY] Kat spell glitch

I was playing a ranked game with Sandstorm Katarina , won my lanes pretty hard, everything was okay, and around 15 minutes into the games, my q, ult and B ( back button) wouldn't work at all! Q would show the range indicator if I removed my smart-cast but it would make a sound if i tried to use it, same went for my ult and B. Everyone was winning their lane pretty hard and we managed to finished the game pretty fast so i was lucky, but i had to rely only on w and e to do anything, my Zhonya was working well tough. If the game would of last longer i would have been really useless, and it would have easily been a 4v5, also i didn't died once the entire game, so maybe dying would of reset the glitch, but i'm really not sure.

This glitched never happened to me on any champs before, please fix that RITO, for my beloved Katarina (or any champs that could be affected! ).
