the order thing was just me taking a blind stab at it. i can't remember exactly the details of the first crash, but i'm pretty both times i issued a C-3-5 on the warspite, after bombers showed up and iota wing was present. the second crash was immediately upon issuing the order; i honestly can't remember if the first was also or if it was a few seconds later. i DO know that both times it crashed, i issued a C-3-5 earlier in the mission that didn't cause a crash. the third play through didn't crash, but i only issued one protect order at the very beginning.
as for the one i posted the log for, i took no action to cause the crash. i was just sitting there listening to the end of mission dialogue. the second crash of this type (the one the log is of) i think occurred right as the final "return to base" would have been said. again, i can't recall if the first (which was in a different mission) was EXACTLY the same, but it was very similar, happening at the end of the mission while i was basically doing nothing.
