my save file turned out to be somewhat "uneven," and I made some changes.
I completed the fourth campaign, fourth mission,
but it only allowed me to start the first mission, but of the fourth
campaign. Still, I'm grateful; I've already completed three,
and now I'll start the fourth mission of the fourth campaign.
It seems Major Whirlwind is right; I should have copied
the entire folder.
תודה שלא עשני אשה
