Lux Bug
About 5 minutes into my game I used my e and after I casted it the slot when grey and I was unable to use that ability for the duration of the game. This lead to the opposing mid laner to easily get ahead. I disconnected and reconnected, logged out, logged back in and it still would not let me use it. I unfortunately was not able to get a picture of my screen, when I pasted it into paint the screen was black.
