Is it possible to complete Targuna quest and mark it as completed?

Question

I've done all missions from the quest, got both Adventurer Backpack and Reliable Ram mount, both achievements and also did all five secondary quests. But even handing in the boat pass to Captain Indigo, the quest doesn't mark as completed on my questlog.

Is it possible to mark it as completed? Is there maybe some mission left to do that no one yet discovered? Or is it only a "bug" which maybe can get fixed?

Answer 1

With today's patch, CipSoft fixed this, and now the quest appears with a green check mark after completing all missions:

We fixed an issue where the players did not get the green check mark after completing the Targuna quest.

Answer 2

No, after finishing all missions the quest still show as incomplete, even with all missions marked as complete. Maybe is a bug or maybe the quest will be updated soon
