For some odd reason Warrior combat discs (primal defense, resolute stand etc...) stop working. You can press the hotkeys all you want and nothing activates. The only thing that seems to reset this is dying. I have had this happen at least 5 times today.
Upon further investigation....if my character moves from one zone to another with a disc active (used primal defense to test this) upon zoning all discs lock up and cannot be used again until I die.

It's been fixed internally, and will require a patch for those changes to go live. Thanks for the report.
