Thread title:
A llama vanished from my secure mob dome, it was name tagged and the other mobs like parrots are still there, but no llama..

Brief Description:
I placed a llama in my biome dome at the town of Poseidon, I then locked the doors to make sure no-one could get in, I tagged all the animals, next thing I know, I log on to find all other mobs are there but the llama.
I took all the following procedures to make sure it wouldn't de-spawn, also, there are no users in the towns that were either active last/this morning or would mess with my llama :3

Instructions:
1. Spawn a llama with a spawn egg.
2. Name tag it and leave it in a secure area where nobody can gain access.
3. Keep checking on it, until it disappears.

How many times did you recreate this bug?:
Um, I only bought 1 egg as I only had enough for 1 egg, as it was 80k.. Rip my money.. Not like I have anything to my name xD So I wasn't able to re-create the bug.

Result:
The llama disappeared..

Expected Result:
The llama to stay happy frolicking about in the dome..

Evidence:
Nope..
