This one comes up a lot when you host your own Palworld server. To fix the Max Pals and potentially other settings that aren't applying correctly via the config on your server, simply follow these steps:
- Update your PalWorldSettings.ini
- Click on the button on the left hand navbar "Generate WorldOption.sav"

- As this file makes it so your dedicated server ignores your config file, we've enabled a feature that will automatically generate the WorldOption.sav file

- The will now generate the WorldOption.sav file automatically every time your server restarts.
You can now have 20 pals per base and other settings that weren't working on the server!
