Description:
You can't scale down any structure with the Advanced Recipe if the result is bigger than a block. You also can't scale up anything if the source structure is bigger than a block. If you try to press the Save icon it won't do anything.

A example structure is posted below. Trying to scale down won't work unless it's to a 32 grid size, probably because it's bigger than a block.

{tiles:[{boxes:[[I;0,0,0,1,1,1],[I;0,1,0,1,2,1],[I;0,2,0,1,3,1],[I;0,3,0,1,4,1],[I;0,4,0,1,5,1],[I;0,5,0,1,6,1],[I;0,6,0,1,7,1],[I;0,7,0,1,8,1],[I;0,8,0,1,9,1],[I;0,9,0,1,10,1],[I;0,10,0,1,11,1],[I;0,11,0,1,12,1],[I;0,12,0,1,13,1],[I;0,13,0,1,14,1],[I;0,14,0,1,15,1],[I;0,15,0,1,16,1],[I;0,16,0,1,17,1]],tile:{meta:0,block:"minecraft:dirt",tID:"BlockTileBlock"},group:1b}],min:[I;0,0,0],size:[I;1,17,1],grid:1,count:17}
