This happened to me in a Normal Blind Pick match on the Summoner's Rift map. Lux e becomes disabled and you are not able to use it for the rest of the game. The e became disabled in the middle of the teamfight when I was spamming it while cc'd. I tried changing hotkeys and it still didn't work. I'm not sure how to reproduce the bug yet.

Edit: Added the game logs for that game.
