[GAMEPLAY] Lux Permanently Losing Lucent Singularity (E)
While playing as Star Guardian Lux in a ranked game on Summoner's Rift, I placed my aoe skill, Lucent Singularity (E), on the floor and immediately proceeded to detonate it. Instead of damage, the AOE effect disappeared off the floor, caused no damage, and removed (E) from my skill set for the entirety of the game. (In a ranked game, in EARLY game, you can imagine this was very upsetting as a solo midlaner who uses (E) for nearly all my damage output and minion kills.)
As Lux: 
- Use E and place the attack.
- IMMEDIATELY press it again to detonate.
- Skill disappears off the rift in both particle and effect.
- No damage was incurred by targets in the area of effect. No "burst" sound effect was played.
- On future attempts to use the skill, it "cannot be cast at this time". Notably, it also is listed as having no skill cost.
- Attempts to disconnect and reconnect will NOT restore the skill. This was attempted.
- Death does not restore the skill either.
- Switching the hotkey used for the skill does not resolve the issue either.
- Proceed to be upset and cry on the inside for the rest of the game.
- Suffer a defeat even though you had been winning your lane prior to losing YOUR MAIN DAMAGE OUTPUT.
Further attempts to recreate this have not been made because it is absolutely DREADFUL to play an entire game without your skills, and it is unfair to your allies that you cannot perform at your best.
