Statistics are broke. The blocks are just TNT, button, and crafting table. Also I think the other statistics are broken.

When updating Minecraft sometimes all the statistics and achievements are reset to zero, see MC-519
Oh, I don't mean those statistics. I mean the blocks. The ones that say times crafted and times used and items.
