Well, I haven't exactly broken the game, but on several occasions, I do encounter a slightly amusing "flaw". It mostly involves any kind of rocket/lander with side mounted boosters. After I have landed, I decouple the boosters at their lowest throttle rate, and instead of floating off into space, they decide to bounce all over the place, occasionally making contact with the ground and getting stuck, while the engines are on. Quite amusing. FIRST!
