Game Breaking Lux E Disabled Bug

[GAMEPLAY] Lux - E Becomes permanently disabled for the game. (I'm dead serious.)

With Lux, if you send out the E and then mash the E again for the earliest activation possible, I have managed to completely disable the ability. This is game breaking as I could not use the ability for the rest of the game and have not found a solution for it. I believe that the ability thinks that the singularity is currently out, but there is no way to activate it. (Darn this spaghetti code! Seriously though, I lost the game because of this.) The ability becomes blurred out, and costs zero mana... Indefinitely.

  1. Send out E
  2. Mash E as fast a possible
  3. Proceed to lose your ability.

As I have only had this happen to me once, I am not sure how to recreate it. One thing that I am sure of is that it was due to me pressing the E button too fast/too soon. Please look into this as soon as possible, I do not want another person to go through that torture.
