• • Issue appears to have been fixed in 14w26c **

Unless it was a temporary glitch or a bad spawn place, the new Endermite does not take any damage (I was using a stone sword when attacking), or fall from gravity.

The endermite was also not making any sounds (Idle).

I was also not taking any damage from it.

Edit: Spawned one using an Egg in 14w26c, seems to be working perfectly. Not sure if it is caused by the Enderman spawning it.

Edit 2: Spawned a bunch of Enderman, they are now spawning them normally in 14w26c. No problems.
