there probably is something i am doing wrong and just beeing stupid but i cant figure it out.

So much for that. Restarted game and did it anpther time and worked. No clue whatsup with that but works now

Get rid of the torches on the sooty marble and inside the crafting area. Those will (currently) cause the multiblock-check to fail.

And snow also makes it not work. Soooo when having built the thing in a cold biome you cna packup and leave basicly

It's changed in the upcoming version.. :P
