Game Freezing Upon World Load

I try to load a world and the game freezes while loading. This has happened twice, both worlds being on creative mode.

What I expected to happen was...:
The world would load.

What actually happened was...:
The game froze on the loading screen

Steps to Reproduce:
1. Start a world
2. Break ALL stone I'm the world
3. Exit world and try to reload.

I finally figured out the problem, so can you look at this again?
