Save Files
It always surprises me when someone says they are stuck and they only have one save file. Keep at least two save files, the more the better so if you ever need to go back because you made a wrong decision, you have a lifeline. : ) I always keep at least three. In the heat of battle, you might not make a good decision. Your previous save file will save you.

Very wise thoughts, which I always follow for safety sake. But as you say- in the heat of battle there may happen that some important moments will be lost forever...
That's even better!
