I've noticed the same thing, the more I do in game the worse the problems get. My game has developed a severe stutter. When I'm building a rocket or trying to fly one the game will pause for about a half second every few seconds, needless to say it's VERY frustrating.

I've experienced many of the issues mentioned here, I just want to add my own experience in hopes that a patch is coming soon. I'm playing KSP EE on Xbox One X with the default radial controls. At first I just had some annoying but recoverable issues 1. When leaving the tracking station, mission control, or the R&D building the game would not load the incoming interface. Instead it would continue to show me the building I was in, while (I think) it thought I was back at the space center. (I thought this because a few of the UI buttons showed). Also one time it gave me a ghosted view of R&D and another UI I don't recognize. (screen shot below) 2. After going to the Mun or other place that took some time to reach I could no longer save or switch back to the space center or tracking station. The times I could get to the tracking station I could not select to fly a vessel and when I would try to quit, nothing would happen. I had no choice but to force-close the game. Then I got hit by what seems to be the big bug. After saving and quitting one time, after my manual save had finished, I turned off the xbox (via the xbox menu) before the title screen loaded. This seems to have caused severe corruption for all saves including the ships. This caused me to lose all my progress, while the game seemed to have loaded my save I could not launch a new ship and I had to delete my profile data both local and online before I could do anything else.
