Weird zombie villager textures and ore textures.

I loaded up the latest snapshot and saw a cave. I wet in and a zombie villager came up. I then saw it had no hands and other broken textures. All other mobs are fine. Also, I noticed that the regular ores have their old textures. (The deepslate ones have the new ones.) Also, I did not change any of the texture or resource packs, this is a vanilla snapshot.
