I unfortunately don't have a video of this incident so i'll do my best to describe it :,)

My friend and I were playing on (I believe metro) and I hid under a desk while he was chased by the butcher. There was a chambler nearby which was why I was hiding. When I knew he was getting close to the train, i went in it and the chambler was there he came into the train and we were unable to close the door with the chambler there. the butcher came, downed both of us, and with both the chambler and butcher still in the train we reset to the beginning with no enemies in the train but both still had our money. Obviously not a problem to us! I just thought I'd mention it. Love the game!
