That galaxy generation button causes the game to crash if you click it multiple times. I have increased the number of systems to 255 and generated a new map. I didn't like how it looked, so I clicked it again to generate a new one. This time the map was created much more slowly. It got slower with each new map, and then after one or two more tries, the game crashed with an access violation.
The reason I kept generating new maps because I don't like to have my warp lines crossing each other. In SEIV, I used to keep regenerating new maps until I got one that doesn't have any warp lines crossing. In SEV, you can't do that because it crashes.
