Bug (Use it while you can):If you select a block in the hotbar, then place the block in your inventory, you can place the block and duplicate the item.
the wiki said as long as the little white foot-on-platform indicator was gone it was fine
Or edit the blockset to give you 999,999,999 blocks for each craft. It actually works.Foot on platform is player <-> object gravity. Red line is object <-> object gravity.
