Quest Bug on Bastok Mission 2-3 The Emissary (San d'oria)

[geekbreath]

I am unable to finish this quest. I have killed Warchief Vatgit multple times and Helaku will not complete my quest. He keeps telling me to do what Halver said, and Halver said not to talk to him any more. All the quest info says is investigate Yughott Grotto which I have done multiple times. Please help as I am unable to progress my rank!

UPDATE: Apologies! This was due to my own incompetence. I was not meant to kill the war chief but to find the Burning Circle and Kill the dragon, I read some incorrect information on how to complete the quest and it did not apply to my situation. I completed it and now have Rank 3!! Thanks for trying to help me.

What exactly did you do. Step by step. What does Halaku say. They should say "go to windurst".

It is a two part mission. You're only half done.

Journey to the Consulate of Bastok in Northern San d'Oria. Speak with the receptionist Baraka, then with Helaku in the back room.
Next go to Chateau d'Oraguille and speak to Halver who is located at (I-9). He will ask you to go to Ghelsba Outpost.
At (H-7) inside the Ghelsba Outpost you will find an Orc by the name of Warchief Vatgit. Defeat him.
Return to the Consulate of Bastok and speak with Helaku again, who will now order you to proceed to Windurst.

Journey to the Consulate of Bastok in Port Windurst (F-6) and speak with Melek, behind the Bastokan Consul door on the right.
Next go to Heavens Tower, located in Windurst Walls (H-7), and speak with Kupipi through the Clerical Chamber door to receive the Key Item Dark key.
Travel to Giddeus, enter Balga's Dais, and examine the Burning Circle to fight the Black Dragon and Seeker.
Afterwards, head back to Port Windurst and speak with Melek again, who directs you to return to Bastok.
Speak with Naji outside the President's Office in the Metalworks to complete the Mission and advance to Rank 3.
You can get the next Mission from Malduc right beside Naji.

I suppose it's also possible that the other city task was already completed, so the one here would be different.

Indeed, what exactly was done before this part, and what do the NPCs say?

As a future note, them bug wranglers here require that bug reports follow a certain template, as seen here:

Welcome to Forum: In-Game Bugs!

That said, though not impossible, it's very unlikely that there is a bug with the mission, and a better forum for this kind of help will be here:

Good luck, and welcome!
