Katarina unable to use Q, R or Recall - not even manually [Gampelay]

I played a normal game on,Katarina, when suddenly the spells Q and R and recall stopped working - meaning nothing happened when pressed. At this time I was 11-0 in kills or something. I tried rebinding the keys, and also made sure that my keyboard worked, and it did. I tried to use the spells and recall manually by pressing the icon, but that also did not work. I clicked"Exit game" and then reconnect, but got the same bug. I did it one more time, this time somebody killed me while i disconnected. I closed the client completely this time before reconnecting. This was also the first death of the game, so I am unsure if the death or the 2. reconnect fixed it, but then all spells worked like normal.
