1) I had a tiny map, and there were only 4 crystals not 5. 2) I can't build additional starbase modules on the crystals, such as weapons or defenses, nor can I group them with regular ships. On any reasonable level of difficulty, this makes the ascencion win practically impossible, since they can be destroyed by a single ship with only 1 attack and no defense as long as it can get to the crystal and make a preemptive strike. Thanks!
