Deleting a saved game file moves the files after it down the memory
unit's list, but the players kept their profiles' old indices. A profile
deleted before the one in use left that one's index naming the next file,
often the next profile made: the profile in use was then saved over it,
taking its name in the list, while its folder kept the new name, which
then read as in use ("a profile with this name already exists") with no
such profile shown. The indices the players and the profile editor hold
now follow their files down the list, and one naming the file deleted is
none.
