We did further testing, here is a twitch highlight confirming the bug: https://www.twitch.tv/videos/808660598 I called the eyes for the other team to shoot, which they successfully did, and then I shot one of the same eyes on the second floor and the challenge failed prompt came up. I can provide more proof from the same stream of duplicate eyes failing the challenge when shot by other people but I feel this should suffice. Additionally, the tentacles were being quite weird (though that could be lag) and many people that were outside the heartstone during queenswalk were not appearing on radar (while I was also outside the heartstone. If you guys could maybe make it so that cheesing riven fails the challenge while you're looking into it, we (the legit riven advocates) think you should have to shoot atleast 1 eye to complete the challenge, which might motivate more people to learn the fantastic fight. <3 My deepest hope is that the riven cheese be made impossible by giving riven's mouth blight damage resistance that would (in practice) double riven's health during the mouth phase but make 2nd damge [redacted to keep the surprise] do twice as much damage to Riven to counter the Mouth blight change. Thank you for your time!

Here is a test we did where the far right most eye had been shot on the lower levels to stagger Riven before getting to the top, and I shot it (without having shot a single eye before) which instantly failed the challenge. https://www.youtube.com/watch?v=ckR10t1W3b8&feature=youtu.be

Hi we did some more testing and figured out that if any eye that had been shot previously (by anyone) was shot again, it would fail the challenge. Here is a video showcasing that: https://www.youtube.com/watch?v=Uoac1FD_Hh0&feature=youtu.be The challenge is meant to be: IF a player has shot the same eye twice THEN fail challenge; now it appears to be: IF an eye has been shot twice THEN fail challenge; other perspectives/tests will be posted soon by the other members of the fireteam.
