"Duplication occurs when someone is successfully resurrected without being removed from the queue. There are no extant cases now that you've merged yours. In the future, if someone is resurrected before processing, the unconscious version in the queue can be automatically merged into the resurrected version without any problems; if someone is resurrected after processing, the version retrieved can be the version that is here, and they can choose whether or not to return. Anyone who has died to this afterlife can choose to return after leaving it."
