Placing an IC2 block into a Blockcraftery frame does the following:
(For example, Machine Block into Reinforced Framed Block)
Frame becomes invisible, all faces of other blocks being contacted become invisible ("x-ray" effect)
A number of these IC2 framed blocks in one area will lag the game when other blocks are added to nearby frames, or when other > blocks are broken/placed.
Blocks are breakable in creative mode, but attempting to break them in survival mode crashes the game. > https://pastebin.com/khSger4s
