Self-affecting powers don't let you enter "combat mode"

[Vanden]

A very annoying bug I remember from live. Normally, using an attack, or just trying to queue one up, puts your character in a "combat" mode for several seconds, where they stay in a fighting stance. After enough time passes without you using an attack, the character returns to the normal idle stance. However, using a self-affecting power like Build Up or Rage when you are not already in the "combat" mode puts you into a broken state where your character refuses to stay in the combat stance. After using attacks in this state, your character will immediately try to return to the idle stance rather than remain in the combat stance, usually before the animation even finishes. The only way to fix this state is to either mash the escape key to force yourself out of combat mode, or wait for enough time to pass so your character leaves "combat" mode naturally.
