don't know if this applies to your issue.
I noticed when editing any of the names within the game, or within reditor, corruption can occur if the first or last name is not listed in the bank of names of reditor.
example, if Avila is not listed under the last name tab in reditor, at some point after further editing of the file, that name may become blank or changed to an other name.
i added all of the last names in the players tab to the last names tab, as well as all of the first names in the players tab, to the first names tab in reditor, and the problem of corrupted names was fixed in my file.
