Put the summary of the bug you're having here
Animals and water are glitchy once you get a couple million blocks away from 0,0

What I expected to happen was...:
Terrain to appear as if it was still Beta in the FarLands

What actually happened was...:
Terrain generation was just fine but water and animals were glitched.
Lava doesn't appear to be affected.
Water glitch appears to be affected by movement of the player and were the player is looking.

Steps to Reproduce:
1. Teleport yourself 13 million blocks away from spawn
2. Find water and animals
3. Observe behaviour
