I built a big rocket with RSS+RO+KJR. After I click launch, when the KJR finishes loading, the timer (T+xx:xx:xx) in the game begins. This means the system recognised that i moved the rocket, but actually i didn't do anything. The will cause the Life Support Mod starts to use resources before liftoff and MechJeb will ignite and release the clamp before I press space. The cause of this might be that KJR makes the rocket move a bit because it's too heavy, and the game thinks that i moved the rocket. Anybody else has the problem?
