Allow it a 1 time move to a settled system.It would also help those who reached their colony limit and cannot build another without taking penalties (assuming no alpha core abuse to ignore limits).
Now compare with system with 2-3 planet, but with creosleeper, the main problem is that such systems seems to be not become unbeateble, less amount of colonies = less system military power, patrols from other systems will not help. So, cryosleeper? No tnx.Not completely true. Some of the patrols will leak into hyperspace, and if the systems are close enough (i.e., in a constellation), then patrols in hyperspace can intercept some of the enemy fleets. True, it may not be totally reliable, but it is some defense.
