I didn't have trouble creating city lights or life on my planets before Alpha 9 or 10. Back then, you could create a planet with an average temp ranging between 50 and -75 degrees Celsius and still create city lights instantly. Since then I have been having trouble creating the perfect conditions for life to spawn. In fact, I haven't even been able to create life since then at all. Is there some new improvement? Perhaps placing organics? Or leaving time to life to sufficiently evolve?
