minecraft 1.2.1 is out

[fodah]

Hey. New here.. First off I just wanted to say that I love the project & you guys are doing great things.

Now, it may be 1.2.3 messing things up, but on the latest revision (354), the server will generate a world, I will be able to load in, and after 3-4 seconds of loading chunks I get the following error on my client:

Is this a known bug with the latest minecraft & latest MCserver?

Thanks, keep up the great work!
