Realm-wide disconnects after nether portal travel.

10-player realms are experiencing a lag when 3+ are online, if a player enters a Nether Portal, it will 9/10 times cause the realm to disconnect every player online.  If it doesn't, the realm will experience a 5 second freeze where the player can still more, but nothing in the game can be interacted with nor chat message sent or received.  This occurs around every 30-40 seconds.
