Krasnikov tube vs Worm Holes and Alubierre Drive

Alcubierre metrics travelling faster than light would run into causality problems under a wide set of circumstances, since they could be used to send messages back in time, especially between observers who are travelling relativistically with respect to one another. I don't know if they would collapse, but in OA void bubbles (which are based on the Alcubierre metric) are limited to subliminal speeds so the problem doesn't arise.
