Is Minecraft's Clone command supposed to not be able to copy IC2 blocks?

  • Ok, Not EVERY block, but anything with actions going on, I think.

    I tried top clone my creative-test fluid reactor, rather than make it all from scratch. All I got were the (static) fluid reactor basic blocks. The reactor inside, the fluid ports / redstone ports / access hatch, all machines attached, and even the cables were error-nuked into black and purple.
