I originally thought that as well, after an explosive stage separation. I had an Apollo-style rocket, the decoupler and sepatrons made things explode, so I turned the service module around and docked, but then I couldn't leave and had to revert. But I don't think that this is the case. I landed on Minmus but then wanted to build a VTOL aircraft, but agian I couldn't leave even though the only parts around were my lander and the mothership in a 20 km orbit.

Yes, and yes. I don't particularly want to start a new save because I have several interplanetary refueling stations and I would like to use them. Also, I don't tnink that this is related to ship count. I have only 10 flights in progress in thuus save but have 47 in my only other save.

Over the past few days I have come across this bug several times. Sometimes, when I want to save something e.g. a base, space station or rover, when I press Space Center, Tracking Station, or Quit to Main Menu, it does the grey-out that tells me that I've pressed the button, but it does nothing. This is particularly annoying since I cannot do anything other than reverting to launch or VAB. F5+F9 or Alt-F5+Alt-F9 don't work either. It doesn't appear to be triggered by anything. The only mods I play with are the Making History Expansion and OPT Spaceplane Parts 2. In the Alt-F12 menu, it tells me: Exception:ArgumentOutOfRangeException Argument is out of range. Has anyone experienced and/or fixed this problem? Thanks in advance.
