Sivir W does not Bounce

EDIT: Apologies; posted in wrong forum (this says Report a Bug, which isnt on the League Gameplay options); if a red would please move this or take this into account, thank you.

Found this out in an autofill bot game where I also experienced the currently existing manaflow band bug. I noticed that, at some point in the game, my W only hit the original target and did not bounce. This happened at level 4 when I first took W as a skill.
