[Plugin: Yet Another Related Posts Plugin] Umm works well with custom post types?

I’d like to know if this plugin is friendly with custom post types. I am using the plugin called: more-types

My custom post types are all sharing from the same default categories, there are no new taxonomies being used for each of my custom post types.

I have my threshold set to 1 at the moment and categories with one in common is selected for the matching, tags, titles, bodies are not considered as I am trying to test out why my custom post types are not being included as a related post.

Could someone please direct me as to what might be the problem?
