Indeed, I reproduced this issue just now on a flight. The inlay shows where in the ocean that I landed after running out of fuel. The ground elevation did go negative for a while, and then readjusted itself to the elevation of the ocean floor before I landed.

Made a probe, and did a test launch, but needed some more dV. Reverted to VAB, and added a stack seperator, tank and engine for a new stage. Saved. Pressed Launch. Follow screen comes up and stays there forever. In the Player.log, it is infinitely repeating the follow in a series over and over forever: [Physics] Object reference not set to an instance of an object at KSP.Sim.impl.RigidbodyBehavior.UpdateToSimObject () [0x00039] in <18c8ac70e67e45869b306b95b90ea034>:0 at KSP.Sim.impl.RigidbodyBehavior.OnPhysicsUpdate (System.Single deltaTime) [0x00012] in <18c8ac70e67e45869b306b95b90ea034>:0 at KSP.Sim.impl.RigidbodyBehavior.OnFixedUpdate (System.Single deltaTime) [0x00017] in <18c8ac70e67e45869b306b95b90ea034>:0 at KSP.Game.GameInstance.FixedUpdate () [0x000b1] in <18c8ac70e67e45869b306b95b90ea034>:0 [Debug] System.NullReferenceException: Object reference not set to an instance of an object at KSP.Sim.impl.PatchedConicsOrbit.get_Velocity () [0x00006] in <18c8ac70e67e45869b306b95b90ea034>:0 at KSP.Sim.impl.OrbiterComponent.OnFixedUpdate (System.Double universalTime, System.Double deltaUniversalTime) [0x00095] in <18c8ac70e67e45869b306b95b90ea034>:0 at KSP.Sim.impl.SimulationObjectModel.OnFixedUpdate (System.Double universalTime, System.Double deltaUniversalTime) [0x00034] in <18c8ac70e67e45869b306b95b90ea034>:0 at KSP.Sim.impl.UniverseModel.FixedUpdateSimObjects () [0x0005c] in <18c8ac70e67e45869b306b95b90ea034>:0 [General] Object reference not set to an instance of an object at KSP.Sim.impl.ThermalBehavior.IUpdate.OnUpdate (System.Single deltaTime) [0x00051] in <18c8ac70e67e45869b306b95b90ea034>:0 at KSP.Game.GameInstance.Update () [0x000bf] in <18c8ac70e67e45869b306b95b90ea034>:0 [General] Object reference not set to an instance of an object at KSP.Sim.impl.SpaceSimulation.IsCelestialBodyCollisionApproximation (KSP.Sim.ITransformModel transform, KSP.Sim.impl.CelestialBodyComponent& collidingBody) [0x0000a] in <18c8ac70e67e45869b306b95b90ea034>:0 at KSP.Sim.impl.VesselComponent.OnUpdate (System.Double universalTime, System.Double deltaUniversalTime) [0x0008e] in <18c8ac70e67e45869b306b95b90ea034>:0 at KSP.Sim.impl.SimulationObjectModel.OnUpdate (System.Double universalTime, System.Double deltaUniversalTime) [0x00034] in <18c8ac70e67e45869b306b95b90ea034>:0 at KSP.Sim.impl.UniverseModel.UpdateSimObjects () [0x00038] in <18c8ac70e67e45869b306b95b90ea034>:0 at KSP.Sim.impl.SpaceSimulation.IUpdate.OnUpdate (System.Single deltaTime) [0x00052] in <18c8ac70e67e45869b306b95b90ea034>:0 at KSP.Game.GameInstance.Update () [0x000bf] in <18c8ac70e67e45869b306b95b90ea034>:0 [Flight] Divide by zero Warning in Vessel SAS UpdateMaximumAcceleration, a component of moment of inertia tensor is zero.

Maybe the door is just jammed on that side. hehe.

Ok I did a post report on this one asking if they could all be moved or if I needed to repost. I don't think I can delete. Let me see if a mod gets it.

Oops I only saw one for KSP1. Can I get a link?

Sadly, rotating wings do not generate lift yet in KSP2

Sorry wrong forum. I need to post this on KSP2 forum.

Over in another thread, a discussion arose about an issue I was having, and I was asked to repost this here in the bugs thread. My goal in testing was to do a redezvous mission. Land 5 kerbals on Minmus in a single mission, and then join them with another 5 kerbals in a subsequent mission. One hundred percent of the time, when you get close enough to the landed ship, close enough for the mechanics to engage, the land ship "falls through the surface of the world" on a straight line trajectory towards the center of that planet. Once it reaches the center, it insta-translates somewhere along that line with an extremely high rate of speed, something like 56,000 m/s or so. This part you all know already as it is posted in another thread. Here is the extra part: If you quickly go to the tracking station after the fall-through, you can "Control" the wayward fall-through ship. Do that, and then gradually accelerate timewarp for a reasonable long time. Long enough to far leave the kerbol system. Choose "Exit Game and Save" When you reload, none of the saves in that campaign will load. Here is a cut-paste from the other thread: I just got around to recreating the campaign that won't load. Tried your suggestion after seeing the list of saves. Sadly none of the saves will load. Using Microsoft Procmon, focused on KSP2_x64.exe, the load appears to be stuck in an endless loop reading the file at: AppData\LocalLow\Intercept Games\Kerbal Space Program 2\backtrace\bt-breadcrumbs-0 over and over from start to end of file over and over. So I do get a chance to load another save from the campaign, but it doesn't matter. Even attempting to load the saves near the bottom of that list results the same. task manager show 7 gigs of free memory with 8.7 in use. KSP2 is using 2.3 gig. Percent CPU usage is only 7%. The reading of that file is only taking 0 to 1% of the SSD's throughput. Using the Analyze Wait Chain function indicates it is running normally, not blocked on anything. Rebooting does not affect it. New campaign works normally. System is a 20 core I9 with 32 gigs overall. GeForce RTX graphics. OS is Windows 10 Pro. At this point a fellow gamer offered to "take a look" at the save files. At that time I had some difficulty understanding what he meant because I had never looked over there before. Actually, while I was waiting to hear from you I was able to 1. Zip up the files at AppData\LocalLow\Intercept Games in the original broken state in case you wanted it. 2. Rename the folder. 3. Start the game, reaccept EULA, save and exit. 4. Using Beyond Compare on the two folders, copy files, except anything in the backtrace folder or either of the Player logs. Then upon starting the game, I noticed that the top 3 saves now had a tag "VESSEL UNAVAILABLE". Skipping those 3, the next one loaded fine, and in fact all ships in orbit are still in orbit, all kerbals are alive and well, and the game is running smoothly again. Let me know if you want the original zip file I made, its only about 6.5 meg or so. And then later I realized this: It would be interesting to know what the vessel was that was unavailable. Reloading the save that worked, all of the vessels are accounted for. There were no others. oh gee, yes I know. The unavailable vessel was the vessel that disappeared that I used to create the situation in the first place. The game somehow still had a memory of it even if I could not see it anymore. Please understand that I am a Principle Developer at a large software company, and so I have some experience with Procmon, Windbg and so forth. Just nothing specifically KSP2 to work with, so in the dark pooking around and guessing. But I am posting this for what it might be worth to you. The "wayward" vessel had eventually disappeared from anything I could detect on the UI, once it was far away and I transited into the Tracking Station. But that vessel was still remembered and the saves somehow caused that bt_bitcrumbs loop to engage regardless of the save I choose until I recopied the whole folder tree leaving that part out.

I am guessing based on what I see. Occasionally on a reload of the whole KSP2 application, after choosing "Quit Game and Save", I will be focused on a craft that will not be visible, and the kerbal inside will be updating madly at a high rate of speed. However, the timewarp setting will appear as the neutral 1x setting. Pressing ESC, and choosing load game, I see that the latest save was an auto-save. Choosing the save immediately prior to this loads properly and all functions as expected. The vehicle is visible and kerbal is normal.

Yes, thanks to you. Had you not asked for it, I would not have even investigated what was inside the appdata folders. Thanks. This will REALLY be a big help, since if it happens again, I won't lose any time. REALLY, THANKS!!!

Need guidance on what to zip. Will I need to zip up the appdata folder path procmon was showing reads from? Or just my portable ksp2 folder? And should I just attach the zip file here? It might be a security issue if others can download from the forum without a purchase.

Sound track is incredible too.

Still working on trying this out, but I had a new interesting experience I wanted to share. I created a rocket and made it fall through the surface. But this time I notice that I was able to get into and control that vessel while it was inside of Minmus. Well, I just turned on my jets and started flying back toward the surface. I throttled upward until I had a 208m/s upward velocity. The negative altitude was decreasing, and when I reached the surface, suddenly it stopped, like a fly in amber. But it is sticking far enough out that I am able to disembark crew. In a strange sort of way this is a successful mission from what I was trying to achieve. I wonder if I can work out the details to build upon this.

ah ok, Let me see if I can figure that out. Thanks......

Meaning an earlier _campaign_ ? I've played all of the campaigns until they reach a point where the campaign itself won't load. Is that what you mean by "save" ? If I can't load the campaign, I cannot get to any save within it.

Valid point. I'm no where near giving up.

Interesting. Can you somehow do this even when you can't load the source campaign? i.e. Can I start a new Campaign and then copy and paste a rocket from one that won't load into another one that will? I'll see if I can figure out how to do that. Any guidance would be appreciated.

I suppose that my viewpoint might also be colored a bit by how I play the game. The things I consider absolutely necessary. I cannot do those things. I cannot land a crew on Minmus, and then join them by another crew on another subsequent mission. The first ship and crew fall through the planet every single time. Nothing I have tried can achieve any sort of permanence. No matter what finagling I have tried, sooner or later it disappears or blows up, and that quite soon. And sometimes, after playing a bit longer, the campaign eventually refuses to load by hanging on the "conics" part of the load. At which point you have to delete the whole campaign and start a new one, and rebuild all of your rockets.

In the video, he speaks of "the occasional bug of ship dropping through the surface to the center of bop and out of the kerbol system". But for me, this isn't just BOP, and it isn't just occasional. It is every single planet, and every single ship, every single time. If there are exceptions it is only that if I try this with kerbin, sometimes the ship will sink into the surface and just stick at some point down under it without continuing to drop further. What I want to do basically, is to land a ship with kerbals somewhere. Once they are out walking around on the surface, I expect them to stay there. However, while they might stay there for a short time, by the time I send my next mission out and then go back to the tracking station, the kerbals and ship from the previous mission are all gone. I can reproduce the dissappearing effect on a single mission much faster......just worked this out and repeated it 3 times this morning. Take a ship with a single kerbal. Land on Mun. Get out, and jetpack away a large distance......as far, say, as the fuel will take you. Look back and note that you don't see your ship any more. Check in the tracking station and note that it doesn't show up there either. I sincerely hope that this is something I am simply not understanding and not doing things right. As far as I know, the COMM thing is turned off. But I have caught those settings turning themselves back on under the hood. Is what I am describing explainable by not having a comm satellite? Surely not just between Kerbin and the Mun. But one question just for the sake of understanding, if comms were enabled, and my empty ship were somehow "out of range" would this make it disappear from the tracking station, and the map view of the planet of another ship in orbit looking for it? Maybe what he means is that it is occasional in the sense that if you land at one spot, and never leave that spot, and never return to that spot in another ship that sometimes it will remain. That MIGHT be true from my experience. But thats really the issue. I am wanting to "build" in any tiny minimal sense, across multiple missions. I cannot do that if I cannot "join" a group from a previous mission.

Ok, that more matches what I am seeing. I know I made it sound like viscosity, and I wanted to believe that also. But in playing with the timewarp, it was like no changes over 3 clicks up, and then suddenly on the 4th click, very rapid changes. Nothing linear about it.
