[Gameplay] Brand's q sometimes disappears

Sorry, I don't know how to reproduce it but I've recently picked up Brand and had it twice so for when I throw my e and w at my lane opponent, but when I throw my q it just disappears right in front on me as if it hit an invisible person but there was no one there. I have a lolreplay file of it actually I think though, let me see and edit if i find anything. Found it but can't get in on here.
