When a player that has custom formatting added by the UsernameHandler chat messages can only be seen by other players who are in the same dimension as them.
Pretty much what is happening is that the UsernameHandler, after formatting the chat message it is sent to all the players in the same world so it just needs to be changed so that every player on the server is sent the message instead.
