What is craft "unloading" due to being farther that the "physics distance" from the "main craft"? What is the best way to deal with it? Can it be avoided?
My problem is this: I have a craft with two probe command modules, one for the rocket and one for a rover. I sent it into orbit around a moon (Laythe). I sent the rover down to the surface. I switched to the space center. I switched to the tracking station. To my horror the rover is nowhere to be found, it has disappeared without a trace!
How can I switch away from my rover without it disappearing?
