I'm hoping that someone can help with this as I felt useless during the cannon fights over the weekend with my first runs through CM. I highlight the cannon, press the button to interact, which brings up a special interaction bar. This bar has one command. I press the right trigger, which highlights that section of the bar. I press the special button, which brings up a circle indicator. I use the right stick to move the circle (which was a horrible idea... it should be the left stick since my right hand is already manipulating the trigger and action button). I can get the circle to turn orange, but pressing the action button again does nothing. There is an indication that the correct button is being pressed, but the GCD never happens and I just sit there, being a total waste of space.

Any ideas?
