So right now I have a problem, which annoys me to the brink of deletion. Ever since I updated to 1.2, whenever I get into orbit, the orbit starts to decay. My periapsis is above 70km, my engines are shutdown and either RCS is turned on or I don't have RCS thrusters. I don't have a surefire way of reproduction, but I know that it happens whenever I place down a maneuver node. It makes it impossible to go to other bodies when it does happen.
