# Objective
- A scene usually gets created using the `SceneBundle` or
`DynamicSceneBundle`. This means that the scene's entities get added as
children of the root entity (the entity on which the `SceneBundle` gets
added)
- When the scene gets deleted using the `SceneSpawner`, the scene's
entities are deleted, but the `Children` component of the root entity
doesn't get updated. This means that the hierarchy becomes unsound, with
Children linking to non-existing components.
## Solution
- Update the `despawn_sync` logic to also update the `Children` from any
parents of the scene, if there are any
- Adds a test where a Scene gets despawned and checks for dangling
Children references on the parent. The test fails on `main` but works
here.
## Alternative implementations
- One option could be to add a `parent: Option<Entity>` on the
[InstanceInfo](
