Description.
The arrows are buggy in the latest snapshot (13w16b). This problem might be related to MC-12133.

Steps To Reproduce.
1. Have a bow (and and arrow if in Survival mode).
2. Shoot it.
3. It shows that it is stuck on the player and after a bit it hits the ground.
4. Its back (the feathers) do not point where they should.

I hope this is not a duplicate becuase I searched for something like this but I didn't find anything.
