Working safely with coauthors plus

I am using your wonderful plugin with another great plugin Co Authors plus, which stores additional authors for posts using an author taxonomy and terms.

I thought I could get the two to work together by using your filter: wp_sweep_excluded_taxonomies

e.g.

function my_func_wp_sweep_excluded_taxonomies($excluded_taxonomies){

$excluded_taxonomies[] = ‘author’;

return $excluded_taxonomies;

}

add_filter(‘wp_sweep_excluded_taxonomies’, ‘my_func_wp_sweep_excluded_taxonomies’, 10, 1);

It still seems to blow away the the relatioship that stores the author though, Id love to get these two plugins playing together so any help would be appreciated.
