Tip: Make it more clear that you are having an issue with the script and need help otherwise your post just looks like spam.

Remove "GmapGenerator." (or replace it with this.) at the top there, since the function is in your script.

Your (npcserver) should also have the following in it's folder rights:

r levels/nalik_caves.nw
rw levels/nalik_caverns/*.gmap
rw levels/nalik_caverns/*.nw

After applying the script it should work fine provided the script isn't broken.
