Hogwarts Map: Ultimate Project/Release 4.0

We are currently doing a full revamp of Hogwarts Castle, and it's currently in Experimental Snapshot phase.

What is the revamp?
The revamp of the castle will take on the design of Prof_Artifex's Hogwarts 2 design. The original template can be found HERE. This will fix a ton of bugs, including a REALLY OLD BUG with the Black Lake generation being broken, due to improper optimization of the map. The map was first worked on BEFORE Mojang added the World Optimization feature.
