Why does my outpost keep vibrating and twisting after landed on the Mun?

[Frank_Black]

Hello everyone~ Here I run into some problems. I accepted the contrast of Mun Outpost and I built a Lab rover and a living space rover and succeeded to land them on the Mun and then I docked them together. But then I found that the confirmation of ‘Landed on the Mun' kept twinkling, and I cannot get the confirmation of 'Maintain stability for at least 10 seconds'. When I get a closer look of my outpost, I surprised to find that my rover keeps vibrating and twisting! Just like a perpetual motion machine! But I was doing nothing! Then I closed the RAS and SAS, released the brake, but they do not work. I was able to move the rover forward or turn, but whenever I stopped, the rover started dancing. When I tried to return to the space center, the game crashed. I do not know why these things happen. Does anybody have ideas?

Are you running any mods?

Sometimes not having enough structural integrity can cause weird harmonics and oscillations in the physics engine. I'd be interested if you landed a copy, except with some more struts added.

Also check your graphics settings. Sometimes, playing the game on low graphics settings (like terrain meshing) can mess with the physics engine as well-- wheels start slipping through the surface and getting stuck, Kerbals flying through small hills, etc.

As ^^ noted, this may be a mod problem, too. All in all, sounds like a bug.

Any chance you could post pics of your outpost? It might help if we're able to see what you're trying to stabilize.

I had this happen once, with a rover that had crashed; There's a thread about it in the Support (modded installs) section. The rover continued to roll in circles without any power source. That's was the least of my problems however. The main issue never was resolved.

Check out the MKS mod for an anchored part. Or KAS has anchors for this purpose. I don't understand it, but I know that it happens to me all the time with large, heavy craft. If you're stock only, landing legs can help instead of just wheels.

I don't know if this is relevant but several versions ago there was a bug that caused an extreme issue with components that had docked once on the ground. They didn't twitch, they actually cartwheeled over and over (just very slowly), propelled by some invisible force. They fixed that issue, but I'm wondering if there is some residual invisible force that's causing the twitching. The cause back then was small hexagonal and small cubic strut parts and their position relative to docking ports. If you had those parts connected between the root part and the docking port then things would go badly wrong. I would suggest, if you have any small hexagonal and/or small cubic strut parts, to remove them from your design and try that.

Do you have SAS or MechJeb on? Turn them off. Try also non-physical time warp. It stops structural wobbling.

This is true, especially the SAS.

Personnally, I've recently noticed somme wobbling (without SAS or SmartAss) on the ground with a SSTO lander that has landed multiple times without wobbling. But the wobbling was very small but noticeable despite the landing struts suspension. It disapeared when lifting off.

If you are running FAR, don't forget to deselect the flight assist buttons. They can wreak havoc, havoc I say!

Are you on a slope? Sometimes things like to wiggle their way downhill, especially if you're using girders/trusses as landing legs. I realize you're on wheels, but it may be the same issue. If you have landing legs on your rover(s) to jack them up, it may help.

[helaeon]

Are there landing legs or wheels on your outpost? It seems that something with suspension is necessary on loading or coming out of time-warp.

I know, I just had to re-build a base so that it would have legs. Exact same base, no legs it bounces itself apart like it's in a bounce house, with legs solid as a rock.

If you leave SAS on it will cause this problem if you told it anything other than "hold position". I've seen the RemoteTech flight computer do the same.
