Breakout Round Loss Glitch (?)

I wasn’t sure where to post this. I was playing in a Breakout match with some friends earlier and something strange happened. My friend traded with someone 1v1 and despite killing the other guy first (it showed in the kill feed and if you slow the video down, he was still alive when the other guy was dead) we still lost the round. No one was experiencing any lag that I remember. It was very strange and annoying. Not sure if it’s some kind of glitch with the hydra or something, but thought I’d post it here. Sorry, can’t lazy link.
