 - Lemonwood Trapdoors face the correct direction
 ## Changes
 - Lemonwood saplings are now obtained through an Entropic Entangler recipe (Stable Entropy + Birch Sapling)
+- Durability calculations have changed to reflect the material's rarity.
+  - Tools have the mining level of the base material with the durability of the next tier.
+  - Hammers get the equivalent durability for the materials put into them. (effectively the durability x6.33)
 
 # Known Issues
 - The Command Core Item does not display the correct texture when activated.
