Our guild cleared Beth, Rhyolith, and Shannox on Thursday 11/08, and when we returned on Friday 11/09, Rhyolith had respawned.
When we cleared the rest of the front bosses and attempted to activate the orb for the bridge, there was no dialogue, and acted as though we did not kill Rhyolith. We were unable to complete the raid without re-killing Rhyolith, and opted not to re-kill because we were concerned about bans/action against accounts for killing the same boss twice in the same raid lockout.
This is definitely a bug to have a boss respawn after being killed, and doubly so when it locks us out of the rest of the raid’s content unless we break the rules.
What are we supposed to do in this situation? Half the raid wanted to kill the boss and see the rest of the instance, since that was the only way to progress.
