The main wall has the Destructible script and references a prefab for the broken pieces. Each of those pieces has the Destructible script and references a prefab based off of their own model. That's the end of the chain, so final chunks do not have any scripts attached. I still can not figure out why the chunks of the original wall never disappear. Instead of disappearing and replacing itself with the broken pieces prefab, it remains in the scene and an infinite number of the broken pieces prefabs spawn out of it. The selected chunk in the image shouldn't exist anymore, but instead it remains and spawns infinite prefabs.
