Was My Save File Deleted?

[Gman123456789098]

While I was in the middle of building a craft in one of my save files, the game crashed(something that happens often, sadly). Since it happens so often, I just went through the usual restarting my Mac. However, when I tried to open my save file, instead of the usual info under the title op0f the file, it says,"just started", and when I try to open the file, it gives me two errors;

1)[Gamepersistence Error]: No ROSTER node found in save state: __ (SANDBOX)

2) NullReferenceException: Object reference not set to an instance of an Object

Does these errors mean my file was lost? Can i get it back? I would really appreciate some help with this!

It means the file is corrupt, looks like the crew roster in particular is borked bad.   If you post what you have someone may be able to reconstruct it to a loading state from your memory of the your crew roster, but no promises, and certainly not me (I'm no good with saves).

Let me just say now, dataloss and crashes suck...  but that's obvious.

If you are lucky, the game has a backup directory for saves too. Maybe it has one in there that isn't too far back?

Look in the backups folder within that save game, there should be some (5 by default) backup persistent save files with date and time information in their names. Grab the most recent version of that, put it in the save folder and rename it persistent.sfs and the game will treat that as your main save file and should (hopefully) load it up again. You might lose a bit of progress but it's better than losing all of it!

To avoid such annoying issues in the future I suggest:

Copy your KSP installation to another folder outside of the Steam directory, outside of program files and program files (x86), e.g. to C:\KSP, and play from that directory, e.g.:

Spoiler

robocopy "C:\Program Files (x86)\Steam\steamapps\common\Kerbal Space Program" "C:\KSP" /mir

Make regular backups of the whole KSP directory, e.g:

Spoiler

robocopy "C:\KSP" "C:\KSP Backup" /mir

Make daily backups of your save games, e.g.:

Spoiler

robocopy "C:\KSP\saves" "C:\KSP Saves" /s
