Is the Bastok quest "The Curse Collector" bugged?

Tried to do it yesterday and the NPC would not finish the quest. I have the quest and the key item. I went to Beadeaux, got cursed and silenced. Warped back to Bastok and talked to the NPC while being cursed and silenced. He did not finish the quest. Followed all the steps on ffxiclopedia.

Am I doing something wrong or is the quest bugged?

Thanks

No one can answer my question? Or did anyone successfully did that quest?

Honestly....sounds like a pretty troublesome quest. especially when you can buy the Poison Cesti for 3k on the AH

Ran into the exact same issue. Additionally, for Beadeaux Smog http://ffxiclopedia.wikia.com/wiki/Beadeaux_Smog I followed the walkthrough very carefully but there was no '???' to examine by the smoke stacks. Are both quests broken?
