I laboured away for ages to create a planet builder, then I send it to a system made of nothing but asteroids.
"Ha,Ha !" I say "Now I can build a new planet every turn". Instead I get a message informing me I can't do it because there are no stars in the system. Now I have to build a star creator. To avoid further setbacks, can the star be built in empty space, or do I need to use it on a storm or asteroid?.
