[2020] Invisible wall in The Tombs mission

Las night I was doing "The Tombs" mission in NY with some nice random fella, and at some point we got the notsonice vissit of 3 rogue agents during the mission. It took us a while but we finally managed to get those bastards... only to find that the game just put some freaking invisible wall in front of us on our way to the infirmary, impossible to avoid. So annyoing and frustrating after that rogue fight, we had to kill ourselves, but yeah, heroic difficulty and no checkpoint so had to restart, again.
