Title: World Anchor crashes the server

Version: 3.0.3/3.0.4

OS: Mac OS X 10.7.4

Java Version: 1.6.0_31-b04-4415

Description of Problem:

Whenever I go to select the world anchor block, there is and "Internal Server error" and it crashes. I am not super good with Java at this point in time.

Also, the world anchor cart has a message of "Item not found" along with stone rail bed.
