Your NPC folder is not "Weird" since it branches off to Pre-re or RE just like your db folder. If you've set your server to Pre-re mode through renewal.h, your server will read all pre-re folders instead of the RE ones. Besides that, for the Izlude map you've shown us, that is now the new RE Izlude: http://trac.rathena....t/16384/rathena.
In your packet_db, do not use 26. Set the version as default.
You setting it to 26 is a bad idea since it's an outdated packet. Default uses the max available version.
default = max available version
