More on orbital instability:

Put a station in orbit around Mun.  Dock a smaller craft (lander) into a side mounted docking port.  Orbit falls completely apart in a matter of minutes.  Apo remained more or less steady at 33K while Pe plummeted from ~30K to 0 and craft crashed into Mun.  What's really odd here is that Apo remained stable while only Pe deteriorated - and it deteriorated fast. 

Verified all engines off.  Disabled all torque. 

Whatever Unity broke in the physics engine, they broke good and hard. 

I can't keep trying to play the game.  I don't have time to continue tripping over broken physics that used to work and are now unpredictable and unstable.

Still getting phantom forces in Munar orbit.  G force bouncing between .002 and .004 with gradual orbital decay. :\

And... game crashed switching back to space center.  If there are any files I can provide to help, let me know.

1.1.3.1289

General --> "Orbital Drift Compensation" on (green).  This is default setting.

After watching craft in orbit around Mun for several minutes in 1x, orbit did decay, but then it magically adjusted itself back up.  Still seeing .002 g force.  Looks like this is a true compensation that dynamically adjusts forces acting on craft to compensate for decay.  Guess that'll work.  Interesting workaround.  Maybe we'll just call it a "realistic compensation for natural perturbation."   Maybe they should put it in the tech tree.  "Perturbation compensator."  5000 science.  heh.

Game ran great for almost 24 hours straight after building three ships and parking a munar ore bot and letting it mine overnight.  Today, was humming along just fine when for no apparent reason, it CTD'd out of nowhere.  Now cannot complete even a simple ship in VAB without CTD after about 10-15 minutes.  I changed NOTHING from the time it was working to the time it stopped working.  Only mods are mechjeb and redux. 1.1.2.1260  Win7 64 8G. 

Been playing since 0.25.  This is by far the most unstable release ever.
