Jugg Tank. I can reproduce this every time I spend a point in an ability tree. Here are the steps to reproduce: Have a group member guarded (usually my wife's Inq Sorc) Gain a level Spend the talent point The game drops the guard when the talent spend animation runs Try to guard the same group member shows the X is already guarded mesage This happens EVERY time. I normally have to log out/back in or travel to be able to guard the same group member again.
