Well, that's plenty of info. Since you don't have any Dynamic Lighting involved, that really cuts down on the possible suspects. Here are some things to check for: 1) All map items are on Map Layer, and not GM layer. GM Layer is invisible to players. 2) Check to make sure that the page your map is on is the same as the one the Player Flag is on. If you rejoin as player, you will automatically see the Player Flagged map, but as GM, you can be on any page. Do you see all the elements properly when you rejoin as GM?
