Riot PLEASE PLEASE disable and fix the stupid bugs on Katarina ASAP!!

Just recently played a bot game with just to get a feel for her and farm more easy IP, next thing I know shortly after 22 mins my recall , death lotus, and bouncing blades stops working!! Had no Harass and Recall and no Ultimate for over 7 mins. Please fix this toxic bug as it's messing up the fun factor of the champion, which in turn messes up the game. Good thing I wasn't playing normals when this happened...
