[2020] Missing Wire Scavengers bug

While escorting the npc to the allies he got lit on fire and died constantly screaming as if burning. With him dead i couldn't progress the mission of escorting him to the trapped allies. I relogged mission appeared to be fresh again. First time the doors to the trapped allies was locked. Relogged again a few times. Eventually those allies were accessible again got to the escort npc walked him downstairs went to "Access the maintenance room and reset the power." The door was open from the previous attempt so i walked in and reset the power. However even after resetting the power the npc stays at the door and the next fight does not initiate. Seems you have to open the door for the mission to progress but if it gets bugged or restarted the door stays open and cannot be completed.
