The Emerald Nightmare last 2 bosses

[Artimadours-agamaggan]

I am trying to complete the raid The Emerald Nighmare on heroic difficulty to complete a quest for Essence of Clarity but i’m not able to get to the last 2 bosses. after clearing the other bosses the portal in the middle of the Core of Nightmare will not open.

Emerald Nightmare: Can't get to Cenarius

After clearing Nythendra and the four wing bosses solo EN N10, the portal to Cenarius is still closed and Malfurion doesn't have any dialog option to open it. This is my first EN outside of LFR, if that matters. There is a support article for this issue, but the suggested fix action (leave instance, reset all instances) hasn't helped. I have a ticket open, but I figured I'd add an official bug report on old content to the QA backlog, in case they start to run out of current bugs to fix.

Sometimes a specific kill order for the first four bosses seems to help.
