I picked a fight with the wizard and quick saved as soon as the combat started. My party wipped and so I exit the game and reloaded. When I loaded back in I was free to move around the room without agro. So I moved the group into the room and positioned them around the NPCs. Then I had to talk to the wizard again to start the fight. Not sure if it is a bug but it sure did make the fight alot easier. So I am sure it could be considered an exploit.
