in the Molensk area of Wayfarer Foothills, this event NPC was behaving oddly before getting stuck
If there were enemy units in the room that the other NPCs were fighting, he would stand there and do nothing, except when I talked to him, he would immediately run over and join the fight instead of opening a dialog. After he finished fighting I was able to successfully open a dialog with him, though. This happened about 4 times, until the last time, the timer on the event turn in ran out and the event ended while he was fighting. And then he returned to his spot and just stayed there forever. Attempting to talk to him while other NPCs are fighting still causes him to join the fights. And he is still there now that I’ve finished making this post.
turns out he doesn’t start fighting even if he’s being attacked, until I attempt to talk to him. He also still solicits nearby players, even though he offers no event. “Hey, got a minute? I have a deal for you.”
