[GAMEPLAY] Gragas unable to use Q for the entire game

Played a ranked game as Gragas () yesterday. Around 15 minutes into the game I was chasing the enemy Elise () down bottom river, and tossed my Q (Barrel Roll) into a brush in front of her while spamming the button to blow it up when it arrived. And it blew up, but the client didn't seem to notice that it did. My Q was then stuck in "Activate to blow up your cask" - mode for the rest of the game (~25 minutes) which we won eventually. Restarting the client (including logging out/in) did not work. Rebinding the key did not help. Casting the ability did nothing, either by keyboard or by mouse-click.

Hope this issue is fixed up quickly, shouldn't be too big of a fix. Good luck!
