I'm getting ready to start a campaign for Lost Mine of Phandelver, and as I am looking at the Cragmaw Hideout map, it appears that my PC will be able to see all the rooms on the map prior to entering the cave. It looks as though the dark areas are blocked in somewhere on a layer, but I can't figure out which layer or how to even delete them. Does anyone know what to do to hid this view from my players? Please help! Thanks!
