it's simple to solve
do it manually
1,use a3ullconver.exe to convert wl.ull to wl.bin
2,use npc2txt.exe to convert wl.bin to wl.txt
3,study wl.txt and teleport.txt of the server side
just open the two file mentioned above
in wl.txt ,you will find each line inculdes 3 colums:
the first colum is the teleport npc's code
the second colum is the teleport information related to teleport.txt
for example, 2 represents it will call the second line's information in
teleport.txt(remember it starts with line 0 in teleport.txt),and you will find this particular line's map code
the third colum is the map code,it should match the map code you find through the second colum
4,when you find the problem and decide to modify it,you can open wl.bin with hex tool to implement your change.
5,convert the wl.bin modified to wl.ull
