Not sure if I'm posting this in the right forum, but I noticed something in the patch notes for 2.1.1, they say that:
"While queued for Nightmare Mode, Group Finder no longer places players into an incorrectly-designated Hard Mode for this Operation. Nightmare Mode has not been implemented."
As far as I know, it is not possible to queue for the Nightmare or Hard mode of any Operation, so I was wondering why it said this.
Seems like a typo
