The bug
In the 1.13 snapshot 17w49a, there is a bug that if you want to craft granite or andesite, it will mix up the outputs for both of these crafting recipes.
That means if you want to craft two andesite with one diorite and one cobblestone, it will put out two granite instead of two andesite.
Also if you want to craft one grantie with one diorite and one nether quartz, it will put out one andesite instead of one granite.
The wood plank recipe's are also incorrect. When crafting planks from logs it will only output on a 1:1 ratio. So you put in one log and you only get 1 plank in return...
