I've been trying to beat the new Purgation operation, but for some reason every time I press the button to open the first door after the swamp, it doesn't open. The terminal is red and says "Access Granted", and the door makes the opening noise, but I can't go through it. I still have the objective marker to press the button, but also the marker to continue on through the mission. Has anyone else had this problem? I'm on PC playing solo too
