Map & Tracking Station Incorrect "landed" status while in orbit causes trajectory to disappear in Map View

KerbalBK · October 16, 2023

This has happened to me, except I don't even see a Ap or Pe indicator when this happens. I'm on v0.1.4.1, no mods.

Nothing seems to fix this for my craft that is currently affected. I've tried going to the KSC, then back to the tracking station to take then control of my craft. I've tried saving and exiting out of the game entirely. And just going to tracking station and then back to craft.

I did some investigation and found some interesting things:

My save opens up straight to the craft in flight. If I go straight to the tracking station and back to controlling the craft, it continues to follow along its trajectory (even though I can't see what that is in map view). BUT if I go to the KSC and then back to the tracking station and take control of the craft, the craft heads straight downward towards Kerbin like all momentum was lost. This is repeatable. Either way I go to the tracking station (straight from flight or from KSC) the craft's state says "landed" in the tracking station. It seems like, at least for me, the game believes the craft is landed and therefore is not showing a trajectory line.

In the screenshot example below I wasn't even in orbit yet, just suborbital:

I would like to be able to provide a save file, I'm just not sure how to do that.

This has been happening to me as well. The craft is fully recoverable from the tracking station and has no orbit lines in the map

A workaround for this bug was to... bring the vessel back! The crew survived, I launched the vessel again and it worked fine.

Anonymous Bug Reporter · December 21, 2023

Hello! I tried to land on the mun for the first time in ksp 2 and it went as well as it could but when I started my craft from the mun I got no nav lines so I'm flying completely blind. Turns out my game thinks I'm still landed on my the mun and I don't know why. the only thing i can think of is that i detached the bottom half of my craft because it had no fuel left while it was still landed and the game thinks it's still attached, so ether it's a bug with decoupler (td - 12 ) not decupeling corctly or bug with me leaving landed part on the mun.

@GradientOGames and @Abelinoss, do you have an orbit line still showing for your craft when this happened? (to check if it’s not related to the landed state bug (or splashed state in this case))

No, I believe the trajectory bug and the this bug are both related to the same issue where the game sometimes doesn't recognise that a vessel has left the surface.

jclovis3 · December 21, 2023

You named two different bugs. The title is for the false ship situation causing the wrong science to be collectable. I have seen this only when reverting to the launch pad after being in orbit with science.

The other one is the reports that new science is available when indeed they are situations you have already turned in. Such an example is Kerbin Atmosphere, or Kerbin Low Orbit which you will keep stumbling in to. That is a separate bug and should be reported in a separate ticket. Part of this one is that the tool tip when you hover over the science button says that you can collect new science but in fact this is not always the case.

Another related issue is the fact that you can't delete experiments that have already been reported after collecting them again. The button to delete at the bottom has an optional toggle which should let you delete everything but that doesn't work either. Individual reports and samples can not be deleted either as there is no button to do so. All of this seems to be simple enough to fix as far as UI and allowable actions with each report. About the only thing that might take more work to fix is not indicating every time you have new science that isn't really new. That might require a plug into the science history if one wasn't implemented. It might have been and just not be connected properly.

When the wrong situation is reported (landed or splash down while in orbit), I found that there are no trajectory lines for the current craft. This means you cannot plot a maneuver either. I had to revert to the VAB to fix in this situation, but I was not far after launch anyway. After I realized reverting to the VAB instead of to launch seems to avoid this bug, I began doing just that every time.

What I expected? Orbital lines to appear when I launch from the mun's surface.
What happened? They did not appear.

How to recreate: Create a lander with two stages, designed to leave the lower stage on the surface and take the upper stage back into orbit, just like the real Apollo missions. Stage the separator and engage the throttle and take it up to 25km. The orbital lines never re-appear on the map.

I think this bug is being caused by the system not recognisingI took off, because there was a separator involved. Therefore it doesn't turn the orbital lines back on.

Severity: Variable. Depending of the player experience and actual situation, this bug can be trivial or a hellscape.

Frequency: Once

Same as the first report. My lander take off from Minmus Monument crater and there are no orbital lines. I managed to get it in orbit manually anyway. Quicksaving and Quickloading doesn't help. Restarting the game doesn't help.

The game consider the vessel to be Landed and not orbiting/flying

Hello there,

it seems like there is still or again a bug regarding the Orbital Lines of a vessel.

This time around only the entry "Situation" was on "Landed" instead of "Orbiting".

I built a fairly simple rocket starting with the starting pod then a science jr a fuel tank and a terrier engine. I added a parachute and landing legs, some batteries and solar pannels in roughly that order. That's what landed on Minimus.

The rocket didn't land upright it fell over, but I took Bill out and walked around a bit and it was fine. I got back in the rocket and fired it up but the orbital lines never showed up on the tracking station or map view. The science window also said that it was in a landed state the whole time. The camera was also not centered on the vessel. I tried to move around the screen but it was centered around a point above the rocket. Quiting to the main menu and reopening the save fixed that issue, but not the lines dissapearing.

I have a save file that you can 100% reproduce the bug from. Just load the quicksave and stage. There is a maneuver planned for an Eve intercept that may or may not have to do with it as the manuver requires you to burn off your metholox before staging and using hydrogen. When I performed the manuver in this way, the bug was avoided. However, if I staged off the metholox tanks before performing the manuver, the bug sets the ship in a landed state as seen in the tracking station and you lose the flight path.

I was on a MUN mission. Lander was two stages. Once landed, my status changed to landed. I used a sm decoupler between the stages. After decoupling and heading back into orbit, the vehicle status remains "Landed". As a result, I get no orbital display in map view. Unfortunately that means Valentina will remain in a low MUN orbit until this bug get's squashed.

Ignoring the invisible orbit lines of the target. It seems the approach/intersect marker is out of sync with the actual position of the craft itself

@Iman_S.5, merged your bug report. I will not ignore the invisible orbit line because that's probably the core of the problem you're having, The game thinks the craft is landed so that's why the marker is not right.

When attempting to ascend from any celestial body excluding kerbin's launch pad, the IsLanded tag is not removed by the game and subsequently the map does not display orbital information, allow creation of maneuver nodes, and other map functions reliant on the game knowing the craft is in flight. Currently, manually editing save file code is only way to remove the IsLanded tag and return map to desired state.

I have encountered the lack of trajectory lines and erroneous landed status twice now (evidenced in one case by the ability to perform landed experiments from orbit).

In the first instance, a simple mun lander that was intended to rendezvous with another craft in orbit experienced some awkward lander-leg snapping/jumping while performing the EVA and got stuck with the landed state. After the navball numbers claimed that I had an orbit in excess of 40km PE, I checked on my rendezvous craft and returned to find that my lander had suddenly lost ALL velocity and was now beginning a plummet straight down. Teleporting the craft back into orbit with the cheat menu actually restored its in-flight status.

In the second instance, I had a lander to decouple from a recovery craft with two stages left; decoupling the lander would take the final stage off the stack while others remained un-fired. As soon as I did this, I lost control over the manned lander and BOTH craft became erroneously landed. I EVAd the lander kerbal and regained control upon re-boarding that vessel. Both vessels were still in orbit at this point. I burned to deorbit the lander and checked the map to find that the rendezvous craft was still too close by; I left the map and watched it plummet right by the lander: it had suddenly lost all of its velocity and started its own plummet. Teleporting the rendezvous craft back into orbit with the cheat menu restored in-flight status. I completed my mun mission and attempted to re-orbit the lander, but the erroneous landed status stuck with it all the way into orbit (confirmed only via navball numbers). Teleporting the lander via cheat menu DID NOT restore in-flight status (I tried twice with different orbits).

FWIW, the rendezvous had to be done nearly blind and the rest of the mission was plagued by faulty RCS thrusters, parachute deployment failure, and was ultimately saved by the unusually-safe-splashdowns bug (50m/s+ landing with 2/3 drogue chutes deployed and 0/3 normal chutes was stressful, to say the least, after all of that). After that session (and looking up the bug), I'll be keeping an eye out for seemingly high-risk moments; maybe I can pull a save or two off that'll reproduce it consistently on my end in the future.

I had the same thing happen (funnily enough, it was immediately after investigating the monument), the fix for me was reloading to a save right before liftoff, then everything worked as expected, so this must be some trigger randomly failing to fire.

Zipnotoad · December 30, 2023

Part of this bug:

But so I can attach my files.

After my own experiences I figured I would make an experimental rocket to trigger this bug intentionally with out-of-order staging, and it works reliably for me with multiple craft designs on the launchpad. I've stuck with the simpler one for reporting here. In the recording, the first launch shows staging through the use of spacebar where even though the craft takes off with a decoupler under its engine, the status of the craft is correct. Reverting and triggering the decoupler first causes the craft to obtain the incorrect "landed" status. This comes with all of the science experiment options and lack of trajectory lines (which I neglected to show in the recording… screenshot it is then) that usually accompany this bug.

Bonus: In the attached save, in "orbit" of the Mun, is a lander which I previously described in the aforementioned thread. It currently sits just over 100km above the surface, has 0 velocity, and is improperly "landed". Taking control over this one curiously does not begin a plummet; instead it starts to slowly rotate in place on my screen while the navball fails to reflect this.
