Name Tagged Mobs Don't Save Their Name After Re-Logging(again)

I have a world originally made under Win 10 Beta, and I recently started up again in it using the newest 1.2 update. My horses from before the 1.1.5 update have always kept their names, but everything from that point on will not keep its name.

I tried naming another horse today, and when I exited the re-entered the world, the horse had lost its name.

However, on a friend's realm, I have two cats and two dogs that have kept their names up until the 1.2 update. Sadly, after the 1.2 update, this realm was lost, with everyone, including the owner, was locked out and couldn't get back in and Mojang could or would do nothing to help us get it back.

So I can't say whether or not this bug still exists in this realm, as the realm no longer exists.

But I just tonight checked on another realm, and my horse lost its name not an hour and a few logouts from when I named it.

I am playing on Windows 10 1.2.2 and I had 24 dyed sheep all named. I logged back in today and not a single sheep still has a name. This is playing on a realm world.

This is still an issue and is happening on my Realm with client version 1.2.3 (using Windows 10)..... Animals are not keeping their names after logging off and back on. Also, name tagged items are not persistent and despawn.

Really ruins building a farm!

On our realm, named villagers loose their name tag and then disappear themselves later.

Same thing in my realm, when I name a mob and when I log out and then back in the mob is no longer named.

It's still happening. Used a nametag on a horse in a realm last night, and it was gone the first time I logged in and out (actually, the server crashed). Still waiting to see whether or not the horse itself will despawn like its predecessors.
