# Objective
- Prevent the case where a hook/observer is triggered but the source
entity/component no longer exists
## Solution
- Re-order command application such that all hooks/observers that are
notified will run before any have a chance to invalidate the result.
## Testing
Updated relevant tests in `bevy_ecs`, all other tests pass.
