New event broke

I was playing the odyssey on the hardest difficulty, I was the last person alive on the last phase for Kayn. Kayn had 20 hp i killed him it killed him. But because i died at the same time it didn't count. Bug or feature?

In my match history it says I killed him twice and that shouldn't be possible on a loss. As well as i was standing in the revive circle and it didn't let me revive until i walked out and back in again???

Please fix.
