Wordpress - Following count not changed

I'm using plugin"Users Following System", you can find below the function to get the following users count, the problem is when the user i follow delete his account the count not changed or updated!

<?php
/**
* Retrieve following count
*
* Gets the total number of users that the specified user is following
*
* @access private
* @since 1.0
* @param int $user_id - the ID of the user to retrieve a count for
* @return int
*/

function pwuf_get_following_count( $user_id = 0 )

if ( empty( $user_id ) )
$user_id = get_current_user_id();


$following = pwuf_get_following( $user_id );

$count = 0;

if ( $following )
$count = count( $following );


return (int) apply_filters( 'pwuf_get_following_count', $count, $user_id );

?>


here is the code i used into the author page

$following_count = pwuf_get_following_count( $curauth->ID );


So how can i update the count of the users i follow if they deleted their account?
