When I'm facing The Fragmented One on SP with a friend, I've noticed on a couple of occasions that when I go into last gasp, after a moment I will get knocked out of last gasp and revive even when I don't do anything. As much as this seems like a bug in my favor, it's actually rather annoying, unfun, and frankly feels unfair. Is this a known bug they're going to fix?
