"Gold Horse Armor" is inconsistent with its ID and all the other golden tools and armor
The infested stone bricks variant are erroneously in singular form, which is inconsistent with the non-infested blocks and the basic infested stone bricks
"Wooden Slab" is vague and potentially misleading, and inconsistent with its ID
"Portal" is ambiguous and doesn't match the current Java name
"Crops" is ambiguous and doesn't match the current Java name
Long mundane potions don't exist in Java, but they should still be renamed for consistency with the other base potions
