I never though of completely removing stuff from your missions permantently -- I don't feel I've the right to do that
(but there are some things I don't understand esspecially about TWT - check your pms)
but I finally isolated something which has something to do with the crash in "The Wheel Turns"...
the crash does not appear if you keep at least a distance 4k-5k to the centauri cruisers ---

EDIT: I ran some other missions including the Vorchan to see if it has something to do with the ship or its weapons - negative on that
EDIT2:
"Slipping the Nose" went without a hitch in the second go -- this time is just sticked closer to the gibralta and the GOD than usual and all of a sudden it works.... wierd
EDIT3:
Warning: Null vec3d in vec3d normalize.
