Ha! I got something worse! I ran out of probes and had already visited 25 planets so I found a planet with Breathable, Low, Moderate, Oceans, Rich. On top of that when I landed it had a metal rich moon, outstanding beauty, and Monumental ruins. But it also had Poisonous Plants and Dangerous animals. I had 639 survivors after landing but they were all killed leaving me with a score of 2889. And I was trying to get a good score.
Also this is not my lowest just I felt I had good odds with this then got a trash score. My lowest is 2200.
