serverconfig.txt. On FREAKHOSTING you change them on the Game settings page. Fields tagged STARTUP (world name, difficulty, size, seed, password, message of the day, player slots, enemy smoothing) are kept on the Startup page and written into serverconfig.txt every time the server starts, so they always win. All other fields are written straight to serverconfig.txt.
Which setting wins?
Example from our test: we changed Message of the day in Game settings while the server was stopped.
serverconfig.txt showed motd= with the new text after the next start, because the Startup value is written into the file each time.
