Already sorted. The artifact doesn't send them back in time exactly. It creates and integrates them into a pocket timeline surrounding an item or event. once the event has played out, the people are returned and the pocket timeline erased. No chance of changing the future. It does send them back in time really, but in a paradox- and loophole-free way.
