I am having an issue when placing either of the two kethane survey parts on a satellite. When i go to launch the craft it shows as if I am already in orbit but yet i never launched the craft and the game goes unresponsive. All it will allow me to do at that point is return to the space center. But if i remove the survey part from the craft then it will go to the launch pad like normal. I was wondering if anyone else is running into this problem and has a solution. I am operating off of a MAC so I don't know if there is a conflict with the operation system and the mod.
