In the save attached is my Death Godlike Bleak walker/Assassin. I created a history where I sacrificed Kana to the blood pool. When Maia asked my watcher what happened to him, I told her I sacrificed him to the blood pool. (Don't judge! Honesty is the only good quality in that character.) On returning to my ship, she left the party and sends the letter. Now every transition in the overworld, Maia sends that same letter. How to reproduce bug: Go from land->ship or from anywhere to the overworld. Really easy to reproduce.
