Just doing regular dungeons. Character is not stunned or under any other effect, but just stands there frozen and unable to take any action for upwards of 3 seconds at a time.
If you are a Templar and using bitting jabs, its a known issue. Maybe scroll the forum here and see if your issue matches another problem. Elaboration on what your experiencing might also help.
I know about biting jabs. Not using that when this happens. Everything on my character just stops working. Can't cast, can't attack, can't drink a potion, nothing.
