Nothing wrong with securing your campaign progress, if you are hit by a crash. I feel far worse for having moments of rage in Medieval 2, when a "good" ally backstabbed me and laid siege to an important settlement as a declaration of War. Those moments caused a horde of "Rogans" to march across the battlemap and put the populace of my dear ally to the sword, or shall we say, gunned down?
The OP: Play like me or you suck...
