Purple Dead/Alive at the same time

So, as i was in my game, i came across Purple, who was a person without a name or a rank. I was trying to talk to him, but all of a sudden the game makes me shoot him. Later on, purple kills me and starts talking to me from the dead. So for some strange reason, his body started dead already, but he had another body that wandered around with no name or rank and could still play. Not sure if this has happened before, i thought i should bring it up.

Yes, currently 'Liberty' has an additional Marine that was added during the last update. It's a glitcha and will be removed in the next Version.
