Okay, I got it working to where it places the additional block beside it and it's great, except for the fact that this block has a tile entity. I like the idea of making only half the block have access to the "furnace".
The issue I have now is that when I break the side that does not have the TE, it just sets the side that does to air. Do you know of how I can drop the correct block with the correct TE?
