BungeeCord rocks 
GameBox now syncs top lists and CookieClicker saves between servers in a BungeeCord-Network. Prerequisites are that
all of these servers have MySQL enabled, are connected to the same database and have the setting mysql.bungeeMode set to 'true'. GameBox is not required to run on the BungeeCord instance itself!
This update includes many changes in top list behaviour. For example, unknown players are displayed in top lists now, since some servers in a network might not know a player, that made a score on another server. CookieClicker now includes MySQL support, which is configured automatically like the GameBox MySQL connection.
