Broken Vi Vault Breaker( Q ) Spell

I have played Vi in ARURF at least 8 times now and every single game her Q spell is very glitchy. At least 1/3 of the time the spell is activated, the channeling of the spell continues for the full duration but the directional arrow for the spell disappears and u cannot reactivate the spell to finish the dash. It keeps you locked in the channeling phase until the full duration in which your character does nothing at all.

I am assuming this is just an ARURF glitch, but it would be nice to play Vi as intended. And not feed enemies because you are stuck in a 4 second channeling phase while your opponent kills you.

Riot, please fix this bug.
