Not sure why yet, but if you use the CSV file, the last line is ignored.
Workaround... put a dummy last line.

Edit: I had a malformed line in the file with an extra ,
This code caused the problem (well sort of)

   $bop_find_array = array_filter($bop_find_array);
   $bop_find_array = array_values($bop_find_array);

   $bop_replace_array = array_filter($bop_replace_array);
   $bop_replace_array = array_values($bop_replace_array);

The two arrays ended up with a different number of elements.
