Title: Forgemodloader crash

Version: 0.5.1

OS: Windows 7

Java Version: 7 update 11

Description of Problem:

placed ic2 machines in creative mode. More specifically the singularity Extractor and induction furnace

*update*

I wish to add that i middlemouseclick/copied the machines that was already placed in my 0.5.2 world, so the block id's have probably changed somewhere along the line.

Seems that when you middle-mouse click some machines it selects an invalid block and upon placing it crashes the world.

The only way to fix this is by using McEdit and removing your last placed block.
