I was a member of this group so let me tell you that I agree with what happened from my side.
-we just beat the BCNM and exited.
-our RDM is happy because an astral ring and great katana drop from wings of fury.
-i hit 'H" to sit down and heal while loot is going to anxious RDM.
- all of the sudden (before RDM gets loot) I see that instead of "in party" i am now "solo".
- i think to myself wtf just happened.
- i quickly reinvite everyone to see if loot is still able to have lot cast upon it.
- all treasure from kill is gone...
-everyone sad
