[Gameplay] Keys Stop Working, Unable to Cast Skills

Hi summoners,

I was hoping someone else is having the same issue as I am. Randomly at times throughout the game, some of my abilities (specifically for me, my W, E, and R) will stop working, and I can't use the abilities.

I did notice something too, however. If I try to type during these times that I cannot cast these abilities, some of my keys will not work either. For example, if I were to type in QWERTY, it'll only show up as QTY, etc. I don't know if this has anything to do with it, but it seems like somehow the keys get disabled for the game. Obviously it isn't the keyboard itself, because... I'm typing.

Also to note: I play on a Mac. I don't know if this is a Mac client issue specifically.

The error seems to occur often during every game I play on Summoner's Rift, but so far, has not occurred to me yet on Howling Abyss. Furthermore, I've had two other friends tell me that their ultimates specifically wouldn't cast, having the same problem as listed above.

Nothing I do seems to solve it, but it goes away on its own after some time.

Thanks, and I hope this issue can be resolved!
