Problem with orbit prediction

[gogozerg]

Hi,

Almost every time I try an Apollo like mission to Mün, I see something that otherwise never happens...

- LEM leaves Mün, rendez-vous with CM. Standard docking maneuver...

- Transfer Kerbals from LEM to CM and dump LEM...

- Thrust to leave Mün orbit...

...there's a problem with patched conics. Nothing displayed after leaving Mün's SOI.

I noticed this in multiple KSP versions or ship designs.

Did I miss something? Because if it's a bug, it would be a rather obvious one that would have been fixed long ago.

Probably a dumb question, but here 'goes...

Have you tried focusing on Kerbin in these situations? It might force a re-display of the patched conics.

Hmm

I use precise node to boost conic limit. You can do the same with a configuration edit.

Are you running any mods?

If you quit to the space center and then switch back to your craft via the tracking station, do the patched conics reappear?

I focused different targets, tried "Control from here" too, but nothing changed.

Yes!

I'm using mods of course, who doesn't. I think I noticed such a behaviour without any mods in the past, but I can't be sure.

Two possibilities I can think of:

#1: You haven't upgraded the Tracking Center; a level 2 tracking center is necessary for patched conics.

#2: If you are using a Kopernicus-based mod, you might actually be exiting to solar orbit if the Mun is very close to the edge of Kerbin's SOI. I'm pretty sure it's happened before when a modder forgot to update Kerbin's SOI.

cant be number one because he has patched conncis on the exit of the SOI. I am going to guess mod related

Of course it's not a problem of building upgrade.

And I can now confirm this bug(?) happens without any mod!

To be sure, I just did a fresh install (redownloaded official Win32 1.0.4). I created a new game, built a dumb Apollo like rocket (oops, forgot the legs on the lander).

I feel it has something to do with rendez-vous/docking maneuvers/control transfer, that's why I detailed my mission in the first post. Because it never happened with simple ships with no lander.
