Sculk Sensors do not detect when a Creaking despawns at daybreak
When a Creaking despawns when the sun comes up (NOT when it's Creaking Heart is broken), the noise it makes does not resister on Sculk Sensors or on Calibrated Sculk Sensors. This can be replicated by placing a Calibrated Sculk Sensor next to a Creaking and waiting for it to despawn when the game clock tells it to. With no redstone power going into the Calibrated Sculk Sensor, the sensor reacts to ALL sounds, but the noise the Creaking makes when it despawns does not result in a reaction from the Sensor, and therefore, it does not emit a redstone signal when a Creaking despawns of "natural" causes.
