After we completed the Ascalon fractal as our 3rd fractal, we remained Charr when we spawned into the Jade fractal. In addition to this, our characters were bugged out and no one could pick up crystals. We then had to kill the boss by slowly killing his tentacles, which resulted in the boss dying, then respawning together with all the initial mobs + 2 tentacles. No chest spawned.
Additional information: My character was in a downed state when we were teleported to the Jade fractal.
Also, if it’s possible to compensate our group with the contents of a difficulty 10 chest, that would be great. We spent a lot of time in there and were absolutely devastated when everything became bugged.
