I'm not sure if it used to do this, but I began noticing it after the update. I'm noticing that my orbit is changing very slightly over time. The orbit is outside of the atmosphere, and the option "Orbital Drift Compensation" is checked, but my orbit still changes gradually over time. The tendency is to lower both Apoapsis and Periapsis, but on occasion I have seen one or the other raised slightly. I have removed all mods and DLC, and I'm still getting this. So it's not being caused by mods. Over the course of 20 minutes, I saw my space station orbit go from 72.6998 km, 72.6686 km | time 1:01 72.6985 km, 72.6684 km | time 1:21 I'll also note that when I started noticing this effect, the space station had an Apoapsis of 72.706 km. Of course, when the vessel isn't being actively watched, it doesn't change, which is expected. When I have Kerbal Engineer, I can see this effect in much more detail. The Semi Major Axis is dropping in a herky, jerky manner. It drops a bunch when you switch in and out of map mode. Of course, I can't be sure if Kerbal Engineer is making the effect worse, but nevertheless, the effect is there without it. Admittedly, it's a very minor effect. But it makes me not want to switch to my relay satellites as they're flying in a very precise orbital formation. Does anyone else see this? Has this always been there? Has it been made worse by a recent update? EDIT: On closer observation, the periapsis dipped and went back up. The lowest point was: 72.6996 km, 72.6682 km | time 1:08 EDIT 2: Using scatterer causes the Semi Major Axis to drop much faster. But a complex vessel with lots of parts that makes it run at a lower frame rate, doesn't change the rate at which the SMA drops. Satellites that are far away from their parent body are unaffected. Strangely, my Gilly satellites are having their SMA raised. Maybe because they are orbiting slower than Gilly is rotating? Another curious observation: My Eve vessel that is in low, circular, polar orbit, has a Ap of 90530 and a Pe of 90520. So nearly circular. The really weird thing is that the Pe and Ap are advancing forward in orbit faster than my ship is orbiting. So the time to Periapsis is constantly increasing, and same for the Apoapsis. The SMA is changing very little, but the point of Apoapsis and Periapsis are moving rapidly. On closer observation, for my Eve vessel, when it's closer to Apoapsis, the Apoapsis rapidly lowers and the Periapsis raises. When it's closer to Periapsis, the Periapsis rapidly lowers and the Apoapsis raises. Physical time warp makes the orbit change extremely rapidly. Within a few seconds of maximum physics warp, my orbit changed to something like 90730 to 90320. OK, simply by quickly switching physics warp from 1x to 4x back to 1x, my orbit drastically changed. It went from 90500 90500 to something like 90700 90300 in one iteration. By doing multiple iterations of this, I managed to raise my Apoapsis to 92000 and lower my periapsis to 88000. I'm pretty sure it wasn't this bad before. A few more iterations and I changed my orbit to 98200 82900. Just by messing with physics warp. Without using any thrust. This is absurd. Can someone please try this and tell me if it's just me? EDIT 3: Started a new sandbox mode, put a simple spacecraft in a similar orbit of Eve, and tried it. No more orbital drifting. No problems whatsoever. I'm wondering if it's because I'm in year 20 of my career mode in my main save? Maybe some part is causing it? Ah, it has nothing to do with the time. I warped until it was 19 years in the sandbox mode. Still no orbit drifting problem. EDIT 4: OK, it does have something to do with more complex spacecraft. I loaded my career mode space vessel into a low Eve polar orbit. The orbital decay returned. Having more crew also seems to affect it. Using the "interior overlay" also makes it worse.

I build an aircraft based on a EE lightning using procedural wings and parts. My CoL is behind my CoM and my trim is reset to 0, at least I pressed alt-x many times. This is strange since it always yaws to the left and it should be symmetrical.

This may already be a topic, but after a quick search I couldn't find anything related. Is anyone else having a problem with extreme instability with docked space-stations and bases? Much more so than any previous version? I currently have a space station around Duna and am trying to piece together bases on Ike and Duna. I first really started seeing this issue with the Space station. If I try to use SAS to hold the station in a specific position, the base would soon start to oscillate back and forth until it eventually ripped itself apart. I tried to disable most of the SAS modules on the various remote guidance units I had on each station piece, but it still seems to wobble out of control. I then built a base on Ike. Put down a ISU converter piece and a driller piece and docked them with a few fuel pipes and a main communication battery. It seemed stable at first, but when I returned to the base after a few days, the station wobbled completely out of control and ripped itself apart in about 3 seconds. I was able to "fast-forward" and resume over and over to keep the station long enough for me to disable all the drills, retract them and undock the drill unit from the rest of the station, but it was a really frustrating process. Is anyone else having problems with really unstable docked stations? Any way of avoiding/getting around this? Thanks!

SO I played the game last in 1.1 and sas was fine no problem worked as it should and kept my rockets flying straight. When after many months I come into 1.2 and decide to launch a rocket I turn on sas and launch. And the rocket has no sas on or so it seems. before sas kept the rocket stable stopped the spinning worked all round as expected. now it acts like nothing is happening, doesn't correct (or if it does it's not helping) wont stop spinning rolling or anything of the sorts and makes the rocket give the ground an unpleasant explosive kiss.
