This isn’t the cleanest of code, but it seems to have solved my issue, hopefully not introduced new ones.

Main problem was that get_post_by_custom_permalink function seemed to always remove trailing slash when trying to lookup custom permalinks. So it is no real wonder why trailing slash permalinks are never found.

/**
	 * Fetch a single post based on the custom permalink value stored as custom
	 * meta data.
	 *
	 * @param string $permalink
	 */
	function get_post_by_custom_permalink( $permalink, $exclude = false, $suffix = '' )
	{
		$post = false;
		if ( $front = $this->front() ) {
			$permalink = str_replace( $front, '', $permalink );
		}

		// Fetch all the public post types to lookup against...
		if ( $post_types = get_post_types( array( 'public' => true ), 'names' ) ) {
			if ( $posts = get_posts( array(
				'post_type' => $post_types,
				'meta_key' => '_' . $this->tag . $suffix,
				'meta_value' => $permalink,
				'posts_per_page' => 1,
				'exclude' => $exclude
			) ) ) {

				$post = array_shift( $posts );

			} else if ( substr( $permalink, -1 ) != '/' ) {
				// Lookup with a slash appended, just in case...
				$post = $this->get_post_by_custom_permalink(
					trailingslashit( $permalink ),
					$exclude,
					$suffix
				);

			} else if ( substr( $permalink, 0, 1 ) == '/' ) {
				// Lookup without a slash prefix, this is the ideal behaviour
				// however the above is required for backwards compatability.
				$post = $this->get_post_by_custom_permalink(
					ltrim( $permalink, '/' ),
					$exclude,
					$suffix
				);

			} else if ( substr( $permalink, -1 ) != '/' ) {
				// Lookup with a slash appended, just in case...
				$post = $this->get_post_by_custom_permalink(
					trailingslashit( $permalink ),
					$exclude,
					$suffix
				);
			}
		}
		return $post;
	}

I seem to be facing the same/similar issue as well.

If my custom permalink contains a trailing slash, I get a 404 error no matter how i access the page.

If I remove the trailing slash from the custom permalink, then both URLS (with and without trailing slash) then work.

How do I set a custom permalink with a trailing slash but WITHOUT a file extensions like: /laws/CA/

I have a reproducible case on my development blog. Would be happy to give access to help figure this out.
