Terror Star moves too slow.

Built my first terror star. Cool looking. Since I was at war with the Torians I thought I'ld try it out. It only moves one movement a turn. Since the closest Torian planet was at least 5 sectors away, the way was long over by the time the terror star got to its destination. It is a great weapon, but takes way to long to get anywhere to be of much value.
