i am still missing 1 mask and 1 key after clearing all the hunters (not from the same hunter) and even if i re run on someone elses world i cannot get the mask/key i need so i am effectively locked out of getting the chest rewards. the hunter with the ducktape mask refuses to drop his key and the 4 man team dropped 2 of the netting masks and did not drop the mask with the .50 BMG hole in it (lucky i belive) and since i have completed them i am locked out of re running them.
