Guild Wars 2

There is a bug that causes a channeled weapon effect,both the visual and the sound,
to keep on playing continuously after it has expired.
This happened again on my guardian mace #3 skill.
I tried to sheath the weapon.
I tried swapping weapons.
I tried un equipping.
I tried WP.
And the only way to make the effect stop playing was to relog and loose my place
in EB and be put back in a long wait queue.
A simple in game command that resets weapon effects would be nice.
