Mundo´s default skin Q bug. It is invicible

No much explanation to provide. I was playing top in a LAN normal game against a Mundo (on his default skin) and whenever he would throw a Q the animation of him thorwing it would play as well as the "hit" animation when it landed, but the actual VFX for the missile woul never appear, amking it very annoying to dodge. Please fix this! I also asked my teammates and they said the VFX was also not showing for them
