Doing a GS prog, we killed both Lokke and Yoln on HM, killed all the adds up to the door for Nahvi, and the door won't open. No one was in combat. All adds were dead. All of us ported out and back in to see if it was maybe just one of that was causing the problem. We ended up just having to reset the instance. Kind of a waste of time to get that far and not have the door open.
