palworld-server-docker: Player Save Data Corrupted on Restart

Describe the bug

Player save data (at /Pal/Saved/SaveGames/0/643B916545D6886A839265911924FBEC/Players/) is occasionally corrupted on server restart.

To Reproduce

Steps to reproduce the behavior:

1. Have a server with multiple players
2. Reboot the server, either with the auto-restart functionality, or docker-compose down && docker-compose up -d
3. Have the players rejoin
4. See players’ save data has been overwritten (timestamp on files are changed to time of server restart) and players see the new character creation screen.

Expected behavior

Restarting the server does not affect the player save data

Actual behavior

Restarting the server corrupts/overwrites the player save data

Screenshots

Restarted server at 10:29 Player data for those two characters is corrupted and has to be restored from backup.

Additional context

This happens very frequently, but not every time. It happens to some users more than others, but I can’t figure out a pattern. Thanks for your help, I appreciate your maintenance of this fun project.
