I am unable to speak to the NPCs to start the world event "The Ghost of Saint Germain". I tried everytime i came across the NPCs. The first time i saw the world event, there was a fight close by which i was a part of. After the fight, i left and went on with other quests, thinking i'd return another time to do the world event. Now, a couple hours of playtime later, the NPCs still seem to be frightened of something, as if it was short after a fight. There are no enemys around.
