I was having problems with my satellite, every time I deployed it, then went to do something else, then came back to it, Kraken made it vibrate violently (+ insane spinning), and it exploded.
This problem started going from 0.24 to 0.25 (I think) and was driving me nuts to this day.
After much testing on the launch pad, here is how to replicate it :
Make a thin central shaft (the 0.375 tons iron shaft or a stack of cubic octagonal struts), then take a Gigantor solar panel and put it to x4 symmetry to the shaft.
Launch craft (hold in place with say, stability enhancer) to the launch pad.
Extend all solar panels
Go to the tracking station and come back to the craft.
BOOM, instant Kraken !
The Gigantors do not like "touching" each other and if placed too close (such as on a thin shaft) will simply self-destruct.
I fixed it on my satellite by adding cubic octagonal struts on the sides just before putting the Gigantor... tested and...
IT WORKED !
Had to share this with everyone. You might not care, but this is one hell of a mystery I am glad to have resolved !
