"Craft Loading Error" - all ships lost

[chunkofwhat]

Hello,

I am running KSP on Steam, 64 bit Windows, completely vanilla, no mods. The game was running fine last night. When I started it up this morning, I loaded my saved game and was met with a barrage of "Craft Loading Error"s at the Space Center screen. The messages read "[Craft name] was not loaded because it had the following parts missing: [part name]". I didn't read them carefully because at the time, I just thought it was some funny little indie game bug, nothing to be concerned about. There were a dozen or more of them. I closed them all out and went to the Tracking Station.

All of my ships were gone. I had about a dozen vehicles all around the solar system and none of them were showing up in the Tracking Station. Rockets, bases, space labs, everything gone.

When I tried loading a vehicle in the VAB, all of my ships had ***Contains locked or invalid parts*** errors below their names. Loading one of them gives the following message:

[indent]Craft Loading Error

Craft Clipper 1.0 was not loaded because it had the following parts missing:

fuelTankSmallFlat

fuelLine

RCSBlock

batteryPack

sensorThermometer

fueltank3-2

engineLargeSkipper

fuelTank2-1

Size2LFB

liquidEngine1-2

I checked my research tree, and it's just the same as it was last night. Any ideas?

sounds... nasty.

Try creating a new sandbox game, and import your broken craft there. See if that fixes them

It might help if you could upload a log file. The sticky in this forum will tell you how.

So, what you describe is what happens when parts are removed from KSP's database of parts. Generally this happens when uninstalling mods, but you said you don't have any. Based on the "parts missing" list, it looks like many your stock parts are missing.

Was there anything else that you did or happened to your computer (or steam install) at the time? If it did, in fact, give those errors, then all of the craft are deleted from that save. I would not load up any more saves from that install till you figure it out.

First, I would make a copy of the entire KSP directory to keep whatever is left safe. After that, inside steam, you can right click on KSP and view the properties. There is a button to verify the game cache. Run that and hopefully it will repair any broken game files. It won't, however, recover your save.

After it fixes the files, you can try loading up another save and see if it works. If so, restore any quicksaves you have from before they were eaten. (Hopefully you have a recent quicksave in there somewhere...)

Good luck,

-Claw
