I just queued for a Classic TW instance and when I zoned in my action bars were completely wiped. I had one action bar with a random set of abilities on it. My other 4 action bars were completely wiped. I thought at first it was an addon issue but I disabled all addons and still everything was gone.
So I have to rebuild my action bars from scratch now.
I’ve never seen this before. I have seen where if you make changes to your action bars and enter an instancce or zone you “lose” those changes. I put “lose” in quotes because if you leave the instance you get them back.
That smells like a data replication issue. This is completely different. Even after zoning out I’ve lost all my action bars. Super annoying.
