Brand Ult R is bugged

Just played a game as Brand vs. a Corki mid. Somehow though, my ult continuously would not bounce. I used it 3 times in a row (with the target being Corki) and all of those times my ult would not bounce to any targets. All 3 times Corki was in a group of minions so there were definitely targets for the Brand ult to choose. Later on, I would use my ult on other targets and it would work perfectly fine and I wouldn't use it on Corki again as I didn't want the bug to mess me up again. While this bug isn't big, it's still game breaking in a matchup like this and should certainly be looked into.

Thank you for your time.
