I've just purchased Ghosts of Saltmarsh module for my game, and have added the first 2 chapters (sinister secret and Danger at Dunwater) to my game. For some reason the maps show up great in the GM's mode, but as soon as I swap to viewing it as a player, there is only a black screen where the map should be, even when I zoom out. Is there something I am missing? I tried to create a new game and had the GoS base module there, and I had the same problem.
