If a Roc spawns near a crumbling brazier, it will constantly try to destroy it by smashing it's face into it. Because the brazier is indestructible, the Roc will keep smashing it forever and only disappear when it gets despawned by getting too far away from the player. A simple solution to this would be to make the braziers destructible.
Steps to Reproduce
Wait for a Roc to spawn next to a crumbling brazier
