All entries in the "Hiearchical links" field view link to the final entry -- they should link to what they say they are.

I added a few lines that fixes it. It would not run more than a few times on an average page so I don't think it's too expensive.

EDITED: scrap this patch, i'll upload a much simpler one. for now:

around line 381:

           // Store the additional information. One term can occur in multiple
           // lineages: when Taxonomy's "multiple parents" functionality is
           // being used.
           $items[$id][$key]['hs_lineages'][] = array(
+            'tid'     => $tid,
             'lineage' => $lineage,
             'level'   => $level,

around line 407:

     for ($i = 0; $i < count($metadata); $i++) {
       $term = new StdClass();
