Space station around mun is moving on its own

[Rob woods]

Something odd has happened to my game. Firstly the solar power array started flipping around and blowing up. Eventually it blew itself apart. I now cannot dock as the station seems to be moving. It is behaving like it is orbiting a small gravity well while orbiting the mun. I get close to it and get my relative velocity to 0. If I wait it starts going away then closer and back away.   The intercept originally said 800 m after the maneuver but the rapidly started going up. 
 

I really want to continue this save but do not think I can. 
 

In windows 10. Tried verifying files 8n steam, and reinstalling. Removed all mods. Same issue.

Sounds like you've had a brush with the Kraken. It is summoned by something unexpected going on in your structure. A picture of your station might help.

One thing you can try is change the autostrut on the parts in your station: first remove it from all parts, then start adding it back to grandparent part on any wobbly bits. Use to root and to heaviest sparingly if at all.

This is normal, if 2 vehicles are in orbit and at 0m/s relative to one another. I'm going to hazard a guess that they're not PERFECTLY in the same orbital plane with exactly the same LAN/ArgPe/Ap/Pe etc, so the orbits will be slightly different, so they will "librate" if one is viewed from the other. Look at map view and set the map so you only see the 2 craft, and compare their orbits traced around the Mun. 

Might I ask, what altitude is the space station? I've found that these effects occur in lower/faster orbits, and if you set a higher orbit, it still occurs but over a much longer time, so you have a much easier time adjusting for it and successfully docking etc.

As for the exploding parts.....

Orbiting at around 125 km. I’ve done about a dozen docking approaches before but this one is different. I set them to zero relative velocity and within a minute of normal time they are about 400 m apart then a minute later up to a km. It is like the station is rotating around something else in orbit. Normally I can get them within 20 m and keep them there. I can barely get them to within 400 m.

Are you using Heavy Autostruts in your station or the vessels that dock on it?As Brikoleur said maybe post a picture, that can help a lot.

When you do the approach, switch to the Station and see if its orbit is Stable, 

Also when you do the approach try time warping just a tiny bit just to pause simulation for even a second and see if that resolves it, sometimes it does.

It turned out the station was fine, but there was something wrong with the latest rocket.  It seemed like the rocket had an engine on a little bit for some reason.  Even with everything off, the PE and AE were changing.  I crashed it into the Mun and took an exact replica of it to the Mun and all is fine now.
