It has happened now four times, since we open the realm animals keep dissappearing with any logic, we got a wool farm perfectly protected and many sheeps has dissappeared, same with some goats we got in our farm, recently happened with a Donkey who has a nametag and with a horse who also has a nametag, we've been loosing animals and we don't know why, we play on a 2 people Realm, I on computer and my friend on Cellphone.
