It appears this is still happening. I am stuck inside the dungeon with the lift. I killed the mother and head to the lift to exit and it just takes me right back to the lift. I hit “T” to teleport out and it spawns me back inside the dungeon. I used the map to travel to a city and it takes me back into the dungeon. I tried to reset the dungeon, but it says it will not effect campaign dungeons and nothing happens.
This is very frustrating. I thought I missed something and spent an hour running around looking for what I missed.
