I was trying to get the landing spot just right for Eve crew mission. I kept missing and missing the target and the last attempt I tried detaching some parts that led to collision meaning I would have to readjust the orbit. This was the third time and it seemed fine every time I tweaked the manuever a little bit.
But when I quickloaded what took 5 seconds became over 2 minutes of loading screen. I press Esc button and find no craft or no manuever node. I tried again and again with similar results. I then stopped KSP shut down the computer (which after rebooting seemed fine.) Restarted and got TONS of errors on the side (usually I only get one and that says Steam not connected usually meaning that my gameplay is not recorded on Steam).
Most of them saying. Part doesn't exist
I try loading up the save with this:
I have spent over the past 2 weeks on this mission so I will do whatever it takes to save it...
I also have more video file just in case if you need more of leading up to the event
