First, I went into some heroics and it didn't show the tank under the Main Tanks panel. I had the profile set to my 5 man, and everything looked normal. No clue why the main tank wasn't working.
Secondly, I entered BWD tonight and all my Spell bindings were replaced/reset. Left click was Target, right click was Set Focus, middle click was Power Word: Shield for whatever reason... I had the correct profile on, the Spells were what they were supposed to be... I had to completely quit the game and re-log on for the spells to come back. Very annoying.
Thirdly, how do I reset Vuhdo to show the new main tanks? Sometimes our paladin switches from heals to tanks and I'd like him to be taken away from the Main Tanks panel if he's healing. /reload ui doesn't work, and I couldn't find a reset macro. /reset vd, /reset vuhdo didn't work.
It will also randomly flash at me (I have "flash bar for incoming damage" turned off..), and my Special Dot - which is the role action - will occassionally disappear.
Finally, and the most important thing, I've noticed that I can't turn my character with my mouse ever since I installed Vuhdo. My middle mouse button keybind, set to autorun, does not work. I can't right click to turn my character and I can't left click to turn the camera. Sometimes jumping around does the trick and "unlocks" whatever the problem is, but its overall VERY annoying.
So all in all, I really like Vuhdo, but it seems so ridiculously buggy for me. I can't figure out how to use it comfortably.
