Talk:Nightmare Mode/@comment-6529438-20130714081453

It is not true that everyone in the lobby must have the mission as nightmare mode for it to be one, Two friends and I did Psamathe where one of them and I had it on nightmare, and the other didn't. Just the 2 of us who had it on nightmare mode clicked on the mission, while the other guy just waited for it to start.

Once we got in, it was indeed a nightmare mission.

So you perhaps want to check again, maybe if only the ones who see it as nightmare vote while the others don't it will still be nightmare.
