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!
