Named Creakings Despawn

Steps to create: (in a realm)

1. Place a creaking heart between two pale oak logs

2. Use a name tag on the creaking that spawns

3. Exit the game

4. Re-enter the game. >50% of the time, the creaking will have despawned

Expected result: the named creaking will still be present

Actually result: the named creaking is gone. On the next nightfall, a new creaking will spawn, indicating the creaking heart is no longer linked to the named creaking.
