I'd like to add an addition to this. Since the Crystals do not stack, you have to place them individually in the pipe GUI. So 4 slots with one crystal each. Upon making the request for the MFE to be made the Crafting Pipe will "stack" the first crystal slot in the GUI. This means the MFE crafting pipe will now say it needs a stack of 4 crystals as well as 3 individual ones. The next time you order it will request 7 crystals, and will add the 3 individuals to the 4 stack giving it a stack of 7. This will continue indefinitely with the stack increasing with each order.Mod Pack: Direwolf20 (1.0.18)

Whats the bug: Energy Crystals not properly recognized by Crafting Pipes when the 'import' button is used in the pipe GUI.
Can it be repeated: Yes
I'm making a automatic crafting set-up using IC2; Compressors, Logistics Pipes; Crafting Logistics Pipe Mk3 and BC Silicon: Advanced Crafting Table, and am attempting to create an IC2 MFE.
The Issue is: If you use the Import button in the Crafting Pipe GUI to import the MFE requirements from the Advanced Crafting Table, it imports the 'creative' version of the Energy Crystal. The item ID and meta data is identical to the Energy Crystal created in a Compressor but the pipe will not recognize the Energy Crystal created in the compressor as the same item as the Energy Crystal in the Pipe GUI (the pipe GUI shows 4 stacked crystals, they don't stack normally). Attempting to remotely craft the MFE results in a "Missing: 4 Energy Crystal" dialog.
Testing this, I found that if you use NEI to give yourself an Energy Crystal and then use that crystal in the Crafting Pipe GUI on the Compressor, you can then remote order the MFE with a successful result, but the Pipe attached to the compressor will not recognize the Energy Crystal created within as the same crystal in the GUI and therefore will not pull it out of the Compressor to send to the Advanced Crafting Table.
Known Fix: Use an Energy Crystal created in a Compressor and place it manually in any Crafting Pipe GUI's. DO NOT use the import button.
Known Fix: After the first order, remove the individual crystal slots in the GUI, leaving the stack that the Pipe created with the order. from that point it will only order the stack of 4 and will not increase the total.
Additionally this bug applies to Lapotron Crystals as well, with the exact same issues and fixes.
