In the recipe book, when trying to see the recipe for a stone tool, it shows that blackstone is required to craft the tool.
How to reproduce:
- /gamemode survival
- /give @s crafting_table
- Place the crafting table down.
- /give @s stick
- Open the crafting table.
- Click on the recipe for a stone sword.
-> It shows that you need blackstone for it
I started a new world in the new beta and when I was going to make a stone sword, it required Blackstone instead of cobblestone
