Crafting Tweaks for BFB

If (like me) you're used to playing with Vanilla Tweaks' crafting tweaks, this datapack adds them for the blocks introduced in Blocks for Builders.

• Stairs recipes produce 8 Stairs instead of 4
• Trapdoor recipes produce 12 Trapdoors instead of 2
• 2 Slabs can be crafted back into 1 block
• 4 Stairs can be crafted back into 3 blocks
