I am going crazy. Is this feat discontinued? I have actually done this 5 times now and no credit given. I have been told do it 6x just to make sure... Didn't work. I was told wait for the Red words to appear then kill him... Didn't work. I broke out the note pad and actually tallied each time the batteries charged and on the fifth one killed him... Didn't work. I want credit for this... How many time do you have to do this feat to actually get credit?
