Bug Report Strange Treasure Chest - Missing Quest

[firemeup]

I'm doing the Hidden Expanse secret questline (Wintertide Hidden Quest Guide) in Wintertide. I've done all the steps and obtained the Frost Key. However, the NPC Nicholas Tolir in Ironfang Heights is supposed to give a quest called "A Giant Investigation". Only problem is, he isn't giving the quest and I can't find any reason why.
I included a screenshot of the NPC and his empty dialouge box.

EDIT: For some reason, the quest ONLY appears after doing a nearby quest from a sword. I'm not sure if this is intentional or a bug anymore. It's not mentioned anywhere

The hidden quest line of the Pendant ends at the camp where the NPC Nicholas Tolir is. So it could be normal that it is a prerequisite for the hidden quest "A Giant Investigation" that Nicholas Tolir gives. We've seen more convoluted explanations for hidden quests in other areas.
