/**
 * Saves the player's locale on {@link PlayerLocaleChangeEvent}, which fires when
 * the server receives a ClientSettings packet, and the locale is different from
 * the current value. The client always sends this packet just after connecting,
 * and Bungee also re-sends the packet on every server change.
 *
 * Because we initialize the locale from the DB on login, we normally won't get
 * this event. It will only fire when the player has actually changed their locale.
