Main quest: Influencing Inquisitors - unable to interact with key-NPC

Time: always
Frequency: always
World name: Ragnarock
Character name: Derek Hale
NPC name: Joellaut
Monster name: none
Class/Level: Black Mage lv 48
Party or solo: solo
In-game time: always
Area and coordinates: Whitebrim Front 13x 15y
Steps:
I start the quest (influencing inquisitors). As stated on my quest journal I have to "question the people of Whitebrim Front". I interact with 3 of the npcs involved. Unfortunately the last one, Joellaut, doesn't have the quest mark over his head, and I can't talk to him, which makes me unable to complete the quest

I know that this is the third time I write about this bug and that you have been investigating the matter. I am also aware that you performed a maintenance in coehertas area on february2nd, but nothing changed. I checked the quest on the same date after maintenance and it was still bugged.
The problem is, being a main quest, I cannot proceed with the story and unlock all the end game features (I.e. Dungeons, quests etc) - which badly affects my gaming experience.

I do hope you'll be able to solve this matter as soon as possible since it's getting frustrating for me not being able to proceed further in the game as well as for you that are dealing with the same problem over and over again (which I'm sorry about)

I'm using a WiFi Connection (speed 100mps) and my Ps3 is a Super Slim (500GB)

I likewise am having the same problem and have reported it a few times :/ It's getting quite frustrating as i'm lvl50 now but unable to unlock any of the later dungeons to join my FC and friends orz.

Greetings Defteros and Marzec,

I am sorry to hear you are having trouble with the Influencing Inquisitors quest and that you are having problems progressing in the game because of a quest npc not interacting properly. However this matter has already been brought to our attention and is currently under investigation by development. I recommend checking Here or Here for any updates in the future!
