Loads another map. As I understand it, you need to specify the correct map.xdb (or specify it somewhere and then indicate its number).
Apparently, it only works in single-player mode in version 3.1, but I haven't found any use for it in the developers' files.
WarpToMap(GetMapDataPath().."map.xdb#xpointer(/AdvMapDesc)", 1)And in the main menu, it says that it failed to load the map, etc.
