I was playing a match, and about half way through we nearly all got killed. Our trapper unfortunately perished and disconnected. Then another player joined us, however something was a little off. Firstly Daisy was frozen in place where her owner died. Completely still for the rest of the match.
Secondly when the replacement trapper dropped in. We were surprised to see that we were joined by something reminiscent of a survivor. Only with a massive minigun, a blue nametag and matching badge. The minigun was fully functioning, did good damage too.
Important to note that the game was warning us about bad connections, and the gameplay might have been affected.
