Kraken ship! - Why?

[RedeyePete]

...... Or have the Kerbals acquired Klingon cloaking technology (Romulan?)

In orbit around Minmus.
Go to fly another ship and it disappears.
Exit the game, go back in and it's gone.
It does not show up in the tracking station,
but in crew it shows that Danlo Kerbin is still piloting it!

Reload the save file and it's back

Comparing saved files before and after it disappeared and
it still shows up in the post file.
All the data from the craft is identical except for:
Small variation in part temperatures
Different orbital location
Suspension location for attached rover.

I did some tests in orbit around Kerbin

Remounted rover, added octo core, but this made no difference.

I discovered that if I stage to the point of removing the nuke stage the craft would remain.

So off I went to apply this to Danlo around Minmus, but he still disappeared (ship too of course)

I staged to the point that the rover was separated, only cupola, Danlo and hangar left.

(Other staging combinations tried too)

I could toggle between the craft, but when I returned with a rescue craft, only the rover was left.

On the cupola the exit was blocked (by parachutes I think) so no EVA option for Danlo.

Better to find this out now and not on Eve.

After thinking about how I was going to rescue Danlo, I had a why didn't I think of this earlier moment

and just reloaded from a save before he went on his mission.

So if you want to have a look at it, here it is:

It is stock except for the Mechjeb controller on the rover.

If you can figure out the problem that would be great.

Otherwise I will build a new one from scratch and hope that the Kraken does not haunt it.

Ok I think I found it.

vesselType = Debris

That's from the craft file.

Now lets see if I can find it in the sfs file

You can change the vessel type in game, when naming the ship. Right click a command pod/part and rename.

You can view debris in the map mode. Put your cursor at the middle of the top of the screen and a little filter will come down. Debris is the very first icon and disabled by default.

Yup I just did that, although it was set to rover and not debris.

I have debris set to 0 and one thought was to increase that to see what happens.

Anyway I changed it to Ship and it hasn't disappeared yet.

Celebrating, or too soon?

[Superfluous J]

Watch out if you have debris set to 0 and a ship you want to keep set to debris, it WILL vanish as soon as you stop looking at it.
