Title: Equivalent Exchange crashes server. Version: 3.1.2 OS: OS X Snow Leopard Java Version: Java SE 6 64-bit 1.6.0_26-b03-384 Description of Problem: I made a map in singleplayer. After a while playing it I wanted my friends to join, so I added the save folder to my Tekkit server. When I logged in, all the Equivalent Exchange blocks was dissapeared (transmutation table and energy condenser). When I try to put any one of the items in my inventory from creative mode, it crashes and says "Connection lost. Out of stream.". Has anyone had the same problem? I started using Tekkit yesterday, so can it be my noobiness? Error Messages: Connection lost. Out of stream. Error Log:
