Exiled Morgana's invisible Q...

Today when I was play solo Jinx bot because we hav two junglers, but one of them afk in the fountain. In the early game, I noticed the enemy Exiled Morgana's Q barely seen when she skillshot. I thought this will be particles & SFX of Q is missing.... I couldn't tell where the q goes, at least i can hear the q sound effect. This needs to be fix ASAP!
