The bug:

In Vanilla Datapack, the Creaking Heart decorator has 1.0 probability to spawn, which means the Creaking Pale Oak can always spawn with a Creaking Heart. However, due to difficult generation conditions (it needs to be surrounded by logs), it often fails to be generated.

Steps to Reproduce:

1. Create a world with the Winter Drop Experiment.
2. Place the pale_oak_creaking feature on the lawn.

   /place feature minecraft:pale_oak_creaking

3. Break blocks to find a Creaking Heart.

Observed Behavier:

In most cases can't find the Creaking Heart.

Expected Behavier:

Always find the Creaking Heart.
