Total mess. I have a Mac so I used Time Machine to bring up an old version but it is still a mess. Pitbull is not accurate at all and I have to dump it in between bosses tonight because I can't tell what is going on. Health and Mana bars are way off.
It was working fine for me and then last night I joined a party with two other people and their portraits disappeared (I was using 3-d portraits). All that was left was giant health/mana bars. ReloadUI brought them back though so I didn't worry too much.
I auto-updated today's Pitbull thinking that maybe there was a problem and that would help it and now when I logged in portraits are totally gone for me and for target/focus etc. I went in to play with the options and Portraits are just gone. There aren't any options to change them in the menu.
