Cannot convert Level.sav

[ShadyGame]

So i had this cheater ruining my server, destroying palboxes from everybody. he even created a new guild where some pals from my server members were all mixed there.

I banned him, and backed up my level.sav and all player data, he cameback and did all again..

I tried to restore my files but when someone joins the server the level.sav resets and we have to start over.

I tried to decompress level.sav to json but i get an error

PS C:\Users\x\Downloads\Compressed\palworld-save-tools-windows-v0.17.1> python convert.py Level.sav
Converting Level.sav to JSON, saving to Level.sav.json

any hope in recovering this? too many hours invested

Same issue now, worked before

my sav file also came back with a likely corrupted exception, is there anything that can be done to fix it?

I had the same issue. I was able to fix the issue by upgrading palworld-save-tools from 0.17.1* to 0.22.0.

I figured it was unlikely to be a corrupted save because the problem was identical for my local save and the save of my dedicated server.

*it is the version currently indicated in the README here
