In my last game, starting from around 40 min, the q skill of my Xerath was not working anymore. I could type the letter q in chat, use all my others skills and items. I could not even use the q skill using the mouse. I have no idea how it happened or how to reproduce it.
Happened to me too once. I think for me it had something to do with me lagging as I charged a shot, and it the graphic got kinda messed up. Luckily, I was playing with my friends, and I was able to exit and reconnect and everything worked fine after that
Well, I was not playing with friends. It was a ranked game and i couldn't leave. I do believe it costed us the game.
This was happening to me a few weeks ago. With Irelia's R and a few other champs
