Creakings sometimes lose sight of targets even when they're activated

When pursuing a player, if said player goes behind a wall, the Creaking may sometimes lose sight of the player and return to wandering around idly until the player is able to be seen again.

Steps to Reproduce:

1. Summon a Creaking by placing a creaking heart
2. Enter survival mode and activate the Creaking
3. Go behind a wall with the wall between you and the Creaking
4. Run around the wall as the Creaking chases you

Expected Result: The Creaking will continue to pursue the player until observed.

Observed Result: The Creaking sometimes loses sight of the player and wanders around until the player enters it's line of sight again.

A video has been attached demonstrating this behavior.
