So my fireteam and I suffered through the most laggy Prison run and then we killed the guy right before the Skolas battle, and that guy killed my friend. We tried to run over and revive him, but we were forced back to the Airlock via teleport. We couldn't go back and get him and the Prison wouldn't load, so he left and tried to rejoin, but it said he couldn't. Is this a bug or can someone not rejoin the Prison?
