Experienced this bug last night, just now getting around to posting it. I dropped the smallest possible moon onto the AI-controlled enemy, and just as contact was made, the game immediately ended with "Connection to server lost". Steps to reproduce: 1) Create a world with a small moon. 2) Progress normally until you get an Astraeus and land on the small moon orbiting the planet. 3) Build the three required Delta-V rockets. 4) Find the enemy commander, and directly target him. 5) Click "Annihilate". Result: The moon makes contact with planet, and the game immediately ends with "Connection to server lost". Expected Result: Victory. Or a draw. I'm not sure if smashing a moon into a planet destroys the entire planet, or just a large area of it.
