The big thing to update is Ace2. I had a ton of problems until I did that one specifically. After that it was simply a case of checking the bugsack for specific mods that gave problems and updating them.
Mazzle, the main action bar isn't switching when you're in combat. It's erratic, sometimes it'll switch, but more often than not, I can switch and the moment I leave combat is when the bar will actually change. Annoying, since I'm a warrior, but I'm going to do some artful rearranging of my skills so that the stance specific ones aren't on the bar that switches.
