A few games i've heard and thought it was specualtion, but last game i have a lux who said her "E" ability wouldnt work. she restarted comp and switched out the keyboard to find out her "E" doesnt work still... said it costed 0 mana, so i think the champion Lux may have someone problems and needs to be looked at... ive heard this about 6 times today and just witnessed it myself.
I wish I could have recorded a video of the Lux game my friend played where this same problem happened to him.
Apparently it happens if you double tap your 'E' Key (to make it go off when it lands) but you die as it's traveling. It causes the spell to glitch thinking you still have to trigger it to explode, which is why it states "0 mana" - and it never stops thinking this, removing the ability entirely.
At least, that's what we've come up with.
This happened to me aswell just now, I think it might have happened as I cast my spell and died. Hope this bug gets fixed soon!
