No other way around of breaking the speed of light limit. But in my understanding that "moves the space" bit is incorrect, rather it compresses space in front of the ship, the ship moves trough the compressed space, and ends up so far it is as if it had traveled faster than light.
Reminds of the "Large Hadron Collider creates a miniature black hole that'll destroy the entire planet if it's turned on" thing some years ago The engine will blow up, it no longer bends space, and it thus returns to normal. If the universe was unstable enough for man-made equipment to damage it, it wouldn't have lasted this long
