cannot complete Order Hall Campaign

[Sillvar]

When I got to the Teensie Weensies! quest for the order hall, I do what I must with the npc's but then they dont count for the quest and I cant progress. I checked in .info and it said it was completed by players with no bugs reports, I also asked another guy while doing it and he said it was working fine. I also tried to reaccept the quest, relog and cleaning my cache file and nothing. Im out of ideas to solve it and that is the only thing stopping me from finishing the story line there

Sit at max range on the wand and spam one of them. Worked for me.
