After a decent trip in the nether, we came back to normal world just to discover that our Cows and sheeps disapeared...But worse, we had a collection of lamas (12) and all of them dissapeared too...

It's not the first time we saw animal dissapear in one of our realms but this time , it's a huge loss as we had lots of animals that dissapeared all at once (and for lamas, we had to travel quite a bit for them)

This bug need to be fixed extremely fast as it's unacceptable to have such a lose (on a paid realm).
