Standard invisible chunk error. It happened to me on my first world gen after downloading the new beta. The second world I started didn't have this glitch.
Looking for a clan..to fill the hole..in my foot...

minecraft is like life, you start by beating wood, explore a lot of new things, settle down a bit, finally get that diamond, and then you life starts to suck and you go through hell
What the **** are you even trying to say?

The problem was fixed for me just by quitting and starting up the game again.
Holy **** that looks weird
I've seen that in SMP A LOT of times.
