Glitch messing up perfect Ike landing

Which means there is some other tiny little disagreement someplace (in my rover) that adds up to .004t

Coffee is the answer..

It might be, but that's a pretty good size coffee urn, to weigh 4 kg.

One final piece of evidence has me now utterly sure that the Kraken is aboard!!

This afternoon I had a little time, so I went back to my mission. After fulfilling my contracts on the ground and collecting what science I could, it was time to return to orbit and dock with the command module.
On takeoff, it acted as if there was a fuel imbalance or something (though I checked that and all tanks were equalized) the craft spun under thrust.. So, determined to survive under pressure, I just let it spin and pulsed the engines every time the navball came around to my intended vector.

At some point (i don't know what the altitude was, I was watching my vector roll over closely) the craft whacked, just like it did while landing.. Sudden impact type of spin..
Oddly, once I gained control again (lots of time, as the Apoapsis was way ahead at this point), the vessel suddenly decided on it's own to fly straight again.
No more trouble with it at all, right up to orbit and a circularize burn..

Weird.
