Title: Possible bug when transferring Tekkit classic savegame

Version: 0.5.1

OS: Windows 7 64-bit

Java Version: 7 (Update 10)

Description of Problem:

I am running a local server, and have copied my saved world from Tekkit Classic into the new Tekkit Lite server. Crashes on login, forces the server to stop. I can't seem to make any sense, could someone try to explain what's wrong?
