I'm okay...I'm...I...ARGH!
EDIT: May as well back myself up providing I don't rage in the process.
Two or three missions which are almost ASSURED to break in about 8 different sections if you aren't flying the right ship, or if you're not flying the right ship with the right weapons and the right equipment, or if you even dare to use a jump drive to cut down the hour travelling time to about 10 seconds, or if you kill the particular groups of enemies who actually have NOTHING to do with any part of the mission after that section.
And even if you can safely tick all of those boxes which should prevent any issues arising, you're going to need some god tier luck for the mission to actually go smoothly, because it can still turn its head around and go "You know what? Nah, fuck you, I'm going to grief you today." *Mission breaks*
God help you if you haven't made a separate save before you start every mission, because if you're using just one and a mission breaks, no matter how many times you reload that save, your mission will brick itself, so bye bye 20 hours of gameplay time, fleets of capital ships and never ending trade empires and hello crappy fighter and 1000 credits.
ARGH.
