Names files

[thatguy96]

Out of curiosity is there any reason why replacing one of the leader files with a modified one would result in the game randomly selecting names from other files? I know none of that level of mucking around is supported, but I tried creating a mirror install of the game and then replacing a number of leader files and when I tested it out, only about half were ones found in the files that I had changed. It didn't seem to be based on length or any other readily understandable pattern, and was picking from all over the board (no discernible pattern in selection of the incorrect names which came from a number of files).

Just wonder if there is any reason for this. Would installing the patches incorrectly have affected this? I've reinstalled and things are back to normal, but I haven't attempted to replace the files again.
