I played the dungeon twice.
first time the prisoners all get lock inside the facility when we got away, so, when i repeated it a second time, i thought, if i stay behind with the prisoners, the game won’t shut me out, so i ran behind them.
But, I did get lock inside the facility and I was like! Woohoo! i am going to get buried in this dungeon. started to say bye bye to party members….
and then i get teleported to the “giant trolly” thing ….
I say! burried us if we failed to get out and have to run the dungeon until we managed to get out alive with all the prisoners!
However give us the rewards :p but not the achievement until its done properly, thanks
