I'd make a better post but a lot of this is covered in the scene editing section of the forums, which is open to the public. Anyways, the reason all maps are called Blank_25 or whatever, is because the game server does not send the map name (the string) to players downloading the map, only the .sco file and the according terrain string. Until TaleWorlds makes a new update for Mount & Blade: Warband, there won't be proper names. I'd put the proper strings.txt up that's on the server, but only a select few would see it.
