1. I play the game on windowed mode.
2. At the time I was deploying multiple missions throughout Kaizer's map.
3. First I sent two landers, then four probes. I would only wait for the loading screen to vanish to press the ESC to launch the next vehicle.
4. When I connected back to the landers the top of the atmospheric entry module was still on them and the landing sequence was working enough to safely land the landers.
