My players keep forgetting about the card reading items
So as per the card reading, the tome of Strahd is in Fiona's possession. My players have been at Wachterhaus twice. They know the card refers to her, but they forgot an item is tied to it.
They killed Izek last session and they will most likely be asking her for their reward soon. She will also attempt to overthrow the burgomaster soon.
How do i remind my players about the item without telling them they forgot?
