It's a problem with the Unitbuff() function built into the blizzard UI. It's returning buffs that are castable, instead of buffs that are castable by you. It will require a patch to fix, it's not an AG or Pitbull issue.
I figured as much. I did some snooping around on several forums, including the official forums, and the Unitbuff() function popped up several times.
Thanks for answering, though. :)
[Edit]It still doesn't explain why it works for some of my friends.
I'm having the same issue as the OP, and it's frankly quite annoying.
the filtering started working when I was out visual range of my party.
I've noticed this as well.
Is there anything that can be done to 'fix' this, or do we need to wait untill a new release/Blizzard update?
Thanks in advance, and keep up the good work.
[Edit]It seems to work for a mage in my guild. I asked him to send me his version of AG_Unitframes, I deleted all my other addons(Just to be sure it wasn't some clash)/saved variables and so forth and installed his version, but still no go.
