Named Creakings Despawn If You're Too Far Away

If you use a name tag on a Creaking, and go around 3,000 blocks away, the Creaking despawns anyway.

Steps to reproduce:

Name a Creaking anything with a name tag.

Go about 3,000 blocks away from the Creaking

Come back to the area where you put the Creaking, and you’ll see that it’s gone.

Expected Result:
Every Creaking is there when you return

Observed Result:

All of the Creakings just despawn, despite being named.
