If anyone could help with this it would be great.
I try to convert L2J geodata to L2D when server loads them on startup,
instead of using geoconverter to convert to permanent L2D files.
Currently by using //geogrid the geodata seem to load,
but diagonal movement is messed up on many locations.
I am prety sure I do something wrong with diagonal NSWE flags.
As you can see on patch I tried to use default L2D values for all blocks,
and then recalculate NSWEs as geoconverter does.
L2D keeps a tight leash on people and favoring people that generated them.
Using directly L2J files will help the geodata development, as they are editable.
With the same logic a geoconverter that supports L2D to L2J can be made.
But I prefer the versatility of loading any type of geodata.
Current patch. Not sure it will match free version.
