Put the summary of the bug you're having here

*What I expected to happen was that I would play on my world with all the features of snapshot- 13w02a

*What actually happened was almost every block ( As far as is known every thing is affected but the chest; which retains regular features, also not affected is the leaves of trees, which are a texture-less green) Items and blocks have turned to a polished white color. I've tried multiple times, to no luck. Sadly, I am not currently aware of my Java version, and that might be the problem :/

Thanks, And No worries! I understand problems will come with snapshots, and for ll we know its my fault :/

Steps to Reproduce:
1. Download Snapshot- 13w02a
2. Log in.
3. Go to world.
