When playing online multiplayer coop on the PS4, my Psyker is unable to move, use powers or even be hurt by mobs after being killed while overwhelmed and overheated. My character is standing with a full health bar but is rendered completely useless until the end of the mission. There are no problems once the mission is completed and another player is able to teleport me to the command bridge. My cousin has also experienced this issue with his Psyker under the same circumstances.
I am unsure if this is a known issue. If it is, I apologize for the repeat post.
