Random Undocking annoyingness

[Scottiths]

So I built a ring station (hardest docking ever) and it looks awesome. I got the idea from one of the pictures in the post your station thread. I had it all docked up perfectly and went to bring a spaceplane full of kerbals up to it. However, upon arrival I found that 2 of the ports had come undone. So i fixed it (and redocked, again extremely difficult). Then I went back to the space center and when I returned the same two docking ports had come undone so I re docked... again. It now appears that every time I return it is always un-docked again...

Whats going on here?

The annoyance factor is compounded by the fact that my computer runs this at something like 2 frames per second. Its 417 parts and I start chugging at around 200. Could that cause random un-docking?

I apologize for not using image code, but for some reason every time I do its just white space.

Just because I like my space plane ferry here is a picture of that (not really important to the thread):

From the looks of things, its tight enough that it shouldn't get completely wocker-jawed that far without some degree of torque on the parts somewhere. Fixing the excess torque issues would probably require a re-design, but basically having SAS on causes torque, as does having command modules (at either end especially). SAS will continually over-correct for the slightest bit of station movement, and the gyros in the command pods will merrily help it out.

On another note, I saw someones cylinder station yesterday also and became very inspired myself. My design is a bit bigger though, but my issues involve part count and trying to de-couple the launch vehicle from the thing without tearing it apart.

The lattice work, all the struts, and the bottom engine matrix and webwork are all supposed to come off. The problem is that entire pieces of the ship just poof and disappear when I decouple things manually, or end up in pieces all over the solar system.

I actually found out that one of those nodes that was all askew was actually labeled as "docked." I undocked it and the station exploded... no idea whats going on. Some bug maybe.
