When I place or mine a Nether Brick Slab, it has the old slab sound, not the new sound.

• Nether Brick Block - New Sound on both Mine/Place
• Nether Brick Stairs - New Sound on both Mine/Place
• Nether Brick Slab - Old Sound on both Mine/Place

It sounds like the dull thud, not the crunchy new nether sounds (which are fantastic, btw).

Thanks!
