I am having a problem with bartender4, pretty much since I returned to the game 1 month ago. The addon works flawlessly but it will not display the "extra action" button. Some examples are: twilight during ultraxion, punt during turtle in ToT, and flying wing after the bird fight in ToT.
When I go into configuration, I can see the small green box where the extra action button would go, I even move it to the middle of the screen, but it never shows up. I can see the garrison ability fine. If I turn off bartender4 during those encounters, then the button shows up with the default blizzard frame.
