Well, here is Jon’s original comment. I think that after you decompress the bin and rename it back to the original, you can use a hex editor (like the HEX-Editor plugin for Notepad++) to edit the values according to the link I put in my first post.

For reference, here is the python script’s source code. All it is doing is decompressing the zlib compression. It’s meant for world_2a.bin, and you run it like python ZLIBDec.py "path/to/file.bin". All credits go to Jon002.

import zlib
import sys
from glob import glob

def zipstreams(filename):
    """Return all zip streams and their positions in file."""
    with open(filename, 'rb') as fh:
        data = fh.read()
    i = 0
    while i < len(data):
        try:
            zo = zlib.decompressobj()
            yield i, zo.decompress(data[i:])
            
            i += len(data[i:]) - len(zo.unused_data)
        except zlib.error:
            i += 1

for filename in sys.argv:
    print(filename)
    for i, data in zipstreams(filename):
        print(i, len(data))
        with open(filename + "-decompressed.bin", 'w') as expanded:
            expanded.write(data)
