Dont know, whether it was reported already, but my Pitbull Party frames totally mix up when changing lead or adding a person to the party. For example, at position 2 the healer is presented with all data correct, but healing this person via mouseover heals the tank. Klicking on it presents the tank too. Other frames are mixed up, too. Reloading the ui doesnt help. Only opening the settigs for pitbull and selecting/unselecting "sort by name" helps a little bit.
Same for raid frames
Same here since today.
