Ved added an extra line to the last script when saving, this should be fixed in a25.
EDIT: It turns out this was confusion caused by the fact everyone has always been saying that you need to have ONE blank line at the end of an internal script without cutscene bars. That line is actually miscounted in VVVVVV, where technically there need to be no blank lines at the end.
