Apparently with the latest vassal update it is now possible to load a game room without selecting a game board. So this is one more way you can end with no map. 4th thing. Apparently with the latest update you can now bypass the select a board screen. Don't. If you bypass it you get no map, at least not until you close game and select new game again.
