Hello, I am playing Phandelver and whenever I toggle "hide full page", so that I can chose which parts of the rooms I want to illuminate when players enter, everything disappears on the players maps except the location of all of the doors in the dungeon. When I toggle "Reveal full page" afterwards, all of the door icons disappear untll a player enters a room where the door would be visible. Any ideas what is causing this and how I can correct it? Thanks in advance!
