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.
