Sorry I forgot to send the link of that game. This is the game match history of that game
Uh, you can't auto attack during her ult. EDIT: OH! You mean you can't use any of those? Yea, I heard that's a bug.
This happened to me just barely in a game, as well. I think it started some time around when I went to try to kill Sion. I used my Q to try to last hit him, but I think Jinx got the kill. Anyway, after that, I could not activate my Q or my R and I couldn't auto attack. Whenever I hit Q, the circle showing the range of my ability would come up and my cursor would change, but no matter what I targeted or if I clicked(I have auto cast on), I absolutely could not cast my Q or my R.
I also couldn't back. It wouldn't work if I used the button on the UI or if I hit b. I tried restarting the game and that didn't work, I tried enabling and then disabling quick cast(I had it on by default before this happened). It did eventually go away after I died and we were able to go on to win the match(Jinx carry FTW), but it was terribly inconvenient since I was absolutely worthless for a good 5 minutes.
I didn't die prior to restarting League, so I don't know if that had anything to do with it or not.
I think it may have gotten stuck when I tried to kill Sion. I'm not sure, though.
