Guild Wars 2

Thanks, everything finally worked out for me. And yay for being able to knock them out manually.

Quest: Lines of Communication personal story for asura.

Every time I have tried to use the amnesia gas, it just disappears and nothing happens. If I unequip my weapons and try, still nothing. I can drop the bundle and it will appear on the ground, then I pick it up and try to use it and it will disappear again. I cannot progress any further on this quest without knocking out a peacemaker with the stuff. If i could bonk one, trust me I would :). Am I the only one with this problem? Am I doing it wrong? Thanks for any help.
