The bug

Within the "English (US)" language selection, the moss-covered block of cobblestone is called "Moss Stone". This is incorrect and inconsistent with the naming of other blocks:

• Cobblestone
• Cobblestone Wall
• Mossy Cobblestone Wall
• Mossy Stone Bricks

This block should be called "Mossy Cobblestone". The lack of the "cobble" part when referring to the moss-covered block leads to a usability issue where it doesn't show up with all the other cobble stuff when searching. Likewise, "Moss" vs "Mossy" is also a problem because if you type in that extra Y, the block will disappear from the list when it shouldn't.
