Need more information regarding the match.
Now playing vs nurse or blight might actually be balanced
As I was able to observe, this seems to happen when there is a bot playing for someone that disconnected from the match.
if you look, there are two Jakes , so I guess Jake is the one who DCed and the bot died.
I'm not sure that's the case, but anyway, it's just a visual bug on that ending screen.
It's visible to survivors as well.
