Izlude map problem

[undeadrex 0]

Hey guys, i'm running a pre-renewal client. Im using the old Izlude map, added in my xxx.grf. When i start the game, i went to izlude map, i realize im having difficulties with walking around.. Im guessing is because when the client reads the .gat files, the client reads my izlude
map, but in game its still using the Original izlude map's .gat.. So what can i do to fix this?? any master sifu here please teach me

You will need to edit your map_cache.dat located in your db/pre-re folder to include the old izlude.gat.

Because the map_cache.dat in the folder follows the new izlude walkable paths.
