Possession Bar - Drak'tharon Keep, Tharon'ja
 

So I can't seem to find a resolution for this one. Leveling an alt and ended up in Drak'tharon Keep, and on the last boss he does a possession, however by bar state never changes. I have the same bar mapped to Vehicle and Possess, and also with Overrirde checked. It has worked with everything else that I do/have done, and this is the first case of having an issue. I am unsure if this is maybe a bug, or there might be something I'm missing.

Got the same issue today, my wife too.

This bar WAS functionning a few years ago, it's still the same... possess is checked, vehicule does function, etc... but nothing changed ;)

It's the way Blizzard is handling the bar in this case; Bartender 4 also doesn't function here.

Erhm, my actionbars work fine on that boss, is BT4 creating buttons from scratch?

nUI's is working. Just tested it. Although that doesn't use Ion Engines.

Hmm. Good question. I have no idea.

Bartender4 uses LibActionButton-1.0 to create the buttons.

At least it's not just me. It's not that big of an issue, but I'm hoping maybe someone found a way to deal with it. I just can't bring myself to let go of Ion just yet as I LOVE this bar mod. Hopefully Maul will be able to finish working on this and have it running for WoD, but if not, I'll have to find something else.
