extra action butons not appear

[cdh555]

For Ultra / Madness, you are just supposed to get the extra button as a seperate frame on the screen and it doesn't touch your cast bars as you still need them.
For DMF etc then yes replace the bar as those actions need to be the ones pressed.

On Madness when green platform is dead the button disappears and the castbars return, then on the final one to kill deathwing the cast bars vanish again.
