Exception: not a compressed Palworld save, found b'der' instead of b'PlZ'

[InyoEndo]

Originally had error of "Exception: not a compressed Palworld save, found b'PlM' instead of b'PlZ'"

So performed the fix here: #209 (comment)

Now getting a new error?

Have you tried running the script from the new directory of the updated dev build provided in #209 ?

I missed that the first time. Running the script from the new dev build of the scripts worked for me.

I ran into this same issue and built a fix that handles PlM format. It uses pyooz for Oodle decompression and works with the latest Palworld saves.

Repo: https://github.com/NFZ-441/Palworld-Co-op-to-Dedicated-Server-Migration-Tool

Supports both PlZ and PlM formats, does character migration + guild fix in one command. Step-by-step instructions in the README.
