Thanks for all responses.
I did not change file names or any text. Simply changed numerical values. Did not add or remove digits, so file size exactly the same. Just changed 7 or 8 or 9 to 1 and 1 or 2 or 3 to 9. I am guessing the problem is that I did not copy all the various subfolders and files into the 01 - First Mod directory.
I have Trinity. I will mod Entrenchment instead of vanilla. As with everything involving computers, any tiny difference from what the machine expects lead to failure. Which is a good thing. When the machines get to the point where they can figure out what we meant and do something different than what we specifically told them to do, we are going to be superceded. So thank goodness that computers are still so literal.
