I'm bumping this back up since I finally got around to releasing those missions.
Get the file and info from
here. Might as well put this stuff in spoiler tags in case anyone complains about it.

Load up mission 8 in 3.6.7 and go about destroying the Mjolnirs. When you get to the fourth one, it will crash at some point while you are attacking it or just after it's destroyed. It's not always at exactly the same time but happens sometime around there. Many of the CVS builds in redmenace's thread don't even get that far and crash right away at the beginning.
In mission 7, at some point after the Amenemhet has been destroyed, it crashes. Again, it's not always exactly at the same time.
As I was putting this together I noticed another issue, this time in FRED2, that caused me to repeatedly lose quite a bit of work. Load up mission 11 in FRED2 and add two new ships of any kind. It will crash. It works okay if I add one ship, exit FRED2, go back in and add the other ship, but that is cumbersome.
