After fighting a boss named Mick Dagger, I have to talk to him for a promotion quest. When I finally defeated him, I accidentally turned my computer off. Now instead of me being allowed to talk to Mick after defeating him, he just comes back as an enemy no mateer what. Any ideas?
Have you fought him again? If not, do so and you will probably be able to continue. If you have fought him again and were still unable to talk to him, check the Quest in your Quest Journal and see if there has been a change or you are directed to do something else. If no change, contact Support using the Help Menu (Orange Question Mark above) to report the problem.
