Lost Save Game / Lost progress ("Contains Invalid or Locked Parts") - Reverted to Previous Save?

[JoeSchmuckatelli]

I logged in today, went to fly a space plane I flew yesterday and the loading screen has the warning "Contains invalid or locked parts".  Googled and found a thread that says "Alt+F2" should display them... Looked like a bunch of collision errors.  So I went about trying to fix them, eventually got bored and tried to launch a space plane I flew last night.

 

Except it says the parts haven't been unlocked yet.  Did some digging, and it seems I've lost my science and tech tree progress.

 

So I went back to my saves file - which showed me at 20% reputation when I saved last night  - and now my save game rep is back down to 11%... and the science I'd earned and the parts I'd unlocked are gone.

 

Has this happened to anyone else? 

 

I had a problem with a game earlier where it locked me in space - could the game have determined it was a corrupted file then reverted me back to a previous save?  The odd thing is that the plane I built was there - same with a rocket I'd built to do suborbital missions, but the loss of tech tree functionality has me stumped, as the game won't let me fly these parts until I unlock them again.

I found the save file location - one has my named game, the other has 'persistent'.  The named game was saved last night when I logged off, the 'persistent' file today.  Named has more kb than persistent (72 vs 63).  Looks like it should be the more advanced file.

 

Unfortunately the persistent file seems to be the one that wants to load.

Hi JoeSchmuckatelli, try loading the save from the KSC menu (press escape or click Menu), named saves are made with alt+F5, and can also be loaded in the flight scene with alt+F9

Also, moved to Support.

That happened to me when I switched to 1.0.5. The new plane parts and reshuffled tech tree borked my save file :/

Okay - quite frustrated.  Since posting I've delved into the save files... and it looks like for whatever reason all progress was lost.

It's weird, really.  The named save file was from yesterday.  The persistent file was from today.  Tried deleting persistent (actually just moved it out of the folder), game would not start normally.  Performed a STEAM integrity check - it found two corrupted files, claimed it corrected them.  Took the named file, copied it to a different location, renamed it 'persistent' and inserted it into the save file location - game started normally... but again, all progress was lost.

 

Something happened to my saved progress.  Whatever that something was, the files are gone - reverted (apparently) to an earlier game state.  The ship files (with parts I can no longer access / are not unlocked at this gamestate) are still there.

 

The only thing I can think of is a bug which occurred when I double clicked on a bit of space debris - and was unable to get back to KSC.  I had to close the game and restart - and this is when all the problems occurred.  See: http://forum.kerbalspaceprogram.com/index.php?/topic/127297-delete-please/#comment-2313411

 

There appears to be no fix for this - I can either continue from the previous 11% spot - where I don't remember what I've done or not, or start a new game.
