Fixes

2 bugs fixed

• MC-15547 – Structures (witch huts, nether fortresses etc.) do not get saved with the world file.
  • In order for current structures (witch huts, nether fortresses, etc.) to be saved to the world file, the player must load the appropriate chunks within the game manually. The game will not automatically scan worlds and update structure data globally. After this is completed, structures will be compatible in all snapshots starting with snapshot 13w37b.
• Fixed a handshake exploit.
