Yesterday while playing, I had a teammate that only had 1 spell.
In championselect it showed nothing but a Blue square.(same in loading screen)
And ingame no one was able to see or click on the spell to see what it was.
As far as I can remember, this is not how it should work.
I have no further explaination why or how this happened.
Till this day i still dont know what spells he is using.
(Looking back to the game through the replay system, hovering over the spell only showed: "Spell Not Found: No spellData found.")
Thank you for your attention!
EDIT: It is fixed, the unkown spell turned out to be ignite!
