Plot hole: At the end of the movie, when Rhett famously leaves Scarlett, she thinks about how she can win him back, and with a smile on her face, says, "After all, tomorrow is another day." Her daughter tragically died a few days before. Scarlett isn't the least bit heartbroken about losing her.
Suggested correction: This is not even a mistake, much less a plot hole. A character not acting the way an audience member expects them to is not a mistake.
It should also be noted that in the 1860s there was nothing unusual about a child dying. In those days, roughly 30% of children in white, well-off families like the O'Haras would die before the age of 5.
