Spawn Structures

Change Log:

• Completely overhauled the generation system
• Added 2 new Starter Structures
• Added a new Config option:
  • "Starter Structure" - Specifies the selection criteria for which Spawn Structure will be generated in your world
• Fixed the Null Point Exception issues resulting from the config file failing to generate correctly

Known Issues:

• When generating a world with "Generate Structures" turned off, the Starter Structure spawns 12 blocks too high in the world. At face value, this sounds like a simple issue to fix, but at this time my efforts to fix it have not yet succeeded... :/
