Vessel disappeared - "Landed at the Sun"

[infinite_monkey]

One of my rovers I left on Minmus disappeared - and according to Tracking Station, it is landed at the Sun... I didn't notice immediately that it's missing, so I don't know in which older save it's still correct.

How can that happen, and what do I need to change in the sfs file to bring it back?

Have you tried flying the vessel? Make a quicksave and try it if you haven't. If it is indeed inside the Sun, and you think yourself quick on the trigger, you could use the debug menu to orbit it. If you aren't attached to it, you could destroy it, refund yourself, and cheat up a replacement. Or destroy it and just call it a loss.

I've seen the issue happen in stock before, but usually, the "Landed at Sun" label doesn't reflect the actual condition; it's merely a Tracking Station graphical error. Usually.

If you put up a link to the persistence file, I may be able to fix it for you.

If I try flying it, the whole solar system disappears :-o I need to restart the game in order to bring it back...

Some log info (the affected vessel is Minmus Malemute Rover):

As far as I remember, the rover was attached to a resource lode from MKS when I've last seen it. It should be consumed by now. Could be the "Rock" in the locks. Maybe that's the reason - it's destroyed but still there?

By the way, the quicksave contains some mods I don't have installed anymore, like FAR and TCA. Is there an easy way to get rid of the modules from the vessels? I don't know if that would help in any way, though.

Should be fixed. Maybe. I think.

Link to Quicksave.

The problem was, it wasn't exactly landed anywhere, so it defaulted to the Sun. Or nothingness, apparently.

 

Enjoy!

Ah... Equilibrium at the answer to all of life's questions...

Thanks for your effort, it didn't work though. So I just enabled respawning and terminated the vessel from the tracking station. Rover is gone, so I'm making a better one  Fortunately, it didn't happen on Duna...
