I rushed to kill Copper Citadel boss for first time before the patch, just in case the freeze nerfs made it harder.  Killed him easy, he dropped loot but then I was stuck in his chamber (the dreadnaught boss), nothing else happened.  No quest completion, or item.  So I tped out then back into his chamber, still nothing.  Put a new map in atlas and it said it failed
