So we killed nightmare cb for the first time and i was hoping for some good loot..

Only to get garbage but more to the point i did over 30 mill damage enough for grandmaster chest, 

Yet only received the lower tier master 

30.84 mill soulstrike

Disappointed i could have used the crystals  for more energy /mino runs 

Hi!

This is possible case when several players try to kill the CB at the same time. One of the players kill the CB and get the damage, while the other players do not get any damage cause CB has been already killed.
