Same error here. I've tried put two Rockomax BACC Solid Fuel Booster. Then, when i tried to put an Aerodynamic Nose Cone on top of one of the Rockomax, with three-fold symmetry, the game crashed and close, without showing any error. I doesn't click with left mouse to put the part, I just moved the mouse there. Also: I'm having an issue with sensivity of camera, it's ULTRA sensivity, forcing me to control with keyboard arrows. (I don't know if the bugs have something in common). I'm not in home right now, but I'll run the game with terminal commands to see if i can get some error or something.
