Duna Base Jumps, Flips, and Crashes Upon Loading (1.7.3)

[Barefoot Friar]

KSP 1.7.3 on Ubuntu 18.04 64-bit.  Lots of mods.

My base on Duna, upon loading, jumps up in the air and flips over, and crashes upside down.  (It does this in very slow motion because Duna takes up a lot of visual processing power, and I can't figure out how to speed it up, but that's another question for another post.)

How do I get this to stop?

I have tried going to it directly from the Tracking Center, and I've tried going to it from the station in orbit.  Both times it leapt about five meters up into the air, flipped over, and crashed to the ground where it rocked and wobbled for a while.  It's built on eight L2 Landing Struts.

It only started this when I tried to adjust the graphic settings to speed Duna up.  I've reverted the changes.

Ooo, just checked my Mun base, which is almost identical.  It jumped up, too, but only about three meters and settled right back down on its legs, though somehow one of the solar panels got knocked off.

How do I fix this?  What is the cause?

Try out this mod, should hopefully help:
