With the Thermal Expansion mod (I believe) the redstone energy conduits are supposed to be able to be picked up using shift+click with a wrench and/or hammer. I have seen this bug where the shift+click wrench from buildcraft doesn't work but I believe the crescent hammer should work. In the current set-up the hammer does not pick up the conduits. Additionally picking up a redstone energy cell, which stores MJ (buildcraft power) does not work and follows the same logic as redstone energy conduits.
Same for the Portable Tank. While you can pick up conduits and the tank with just a pick, eventually, you lose what's in them while normally the point of TE is that you keep the power/lava/whatever inside the items. This is kind of a key game breaking bug since the portability and value keeping of these TE items is the whole point of the mod. It's kind of like if an MFSU wouldn't hold a charge in IC2.
The bug, sadly is purely server-side, so until sk has the time to fix it, there is nothing we can do. I agree that the whole point on thermal expansion is lost with this bug and it's functionality. But we'll just have to put up with it.
