Fractals Volcano glitch
Had this happen a few days ago on the lvl 10 daily. Since it was our last fractal before jade maw, we decided to try and get through it. Had to leave 3 people down where the shaman should be at his altar to protect the villagers, which i learned was required or instakill. The other 2 ran back and forth with rocks to break the shield. After his shield broke, he still stayed at the beginning. All of us came up to fight him. I guess his shield during this stage is on a timer because by the time one guy went down to get a rock and came back up, it broke on its own. After defeating him on this part, he continued with the normal cutscene of jumping in the lava and spawning at the end. It took us a while to get through those first 2 stages, but at least we were able to finish without having to reset new fractals.
