During the mission The Great Vault on the map ‘Cathederal of the twin gods’ the minimap’s fog of war won’t work. Also the Planet name and map name display errors.
The Fast travel station has the fog of war around it . I cleared the whole map, went in and out of the map ‘the great vault’, then save quit. It respawned me back at the start of the map - near devils razor. It fixed the fog of war, but the planet name and map name are still broken.
