One of those bank robbery ones or something - the team all left and I cannot finish it on my own yet the "Leave Group" button does nothing and I cant leave the instance - if I log on and off I am right back in the mission.God I miss COH so much.
Do you know how to contact Socrates? Get out of combat and hit the Socrates symbol on your minipap in the upper right hand corner of your screen. There's an option there for leave map. (You can also use it to exit missions similar to COX's "Exit" button.)
