Map Data is unused for character movement (and sucks in general)
Best I can tell nothing really checks for valid client movements compared to the map, blocked cells etc.
Smitty attempted to fix this and realized the map data we have is too inaccurate to use for this purpose. NPC's can get away with it but it really screws players.
I assume the older map dumping tools we used to have were inaccurate or flawed and can't be used to fix this. I also question the legality of doing it that way.
I think I have a plan to mostly automate the rebuilding of perfectly valid map data without dumping anything from the client. This isn't at the top of my priority list yet but will be. For a fully functional server, this is a necessity
