Not part of that instance's group?

I finished a BFD raid about two hours ago. I would like to go back in and loot the enchanting mana oil recipe, but when I enter the instance it says “You are not part of this instance’s group and will be teleported in 1 minute”.

What gives? Why can’t I enter my own raid instance ID?

Someone is likely holding the instance for clams. I had a pug group leader hold the instance hostage when I was trying to do the same yesterday. I just came back the next day and did it, but reset is tonight so your screwed sorry :frowning:
