There have been TWO previous competitive rulings on this cam that are pretty big news, and its pretty clear that its a glitch.
Yes, riot should have fixed it, but VK should not have used it. They knew it was an exploit and still used it.
I do think the last round should be replayed, so VK still have a chance. It's possible they didn't notify VK during the event because they didn't clearly see/notice the cam.
