 My taxonomy is e.g.

 {{{
 -term 1
 --subterm 1.1
 ---subterm 1.1.1
 --subterm 2.1
 --subterm 3.1
 -term 2
 -term 3
 }}}

 and lets say i am on the 'term 1' page and i want to return all suterms.
 But when i run

 {{{
    $args = array(
         'style'              => 'list',
         'title_li'           => '',
         'echo'               => 0,
         'hierarchical'      => true,
   'depth'             => 2,
         'taxonomy'           => 'my_taxonomy',
   'orderby'             => 'count',
   'order'             => 'DESC',
   'show_option_none'   => ''
   );

    $args['child_of'] = $current_term->term_id;

 }}}

 it return only

 {{{
 Subterm 1.1.1
 }}}

 Problem is that

 {{{

   'orderby'             => 'count',
   'order'             => 'DESC',
 }}}

 when i put it out, it works as expected

 BTW IMO wp_list_categories() need some bigger rewrite - it is probably the
 oldest code in WP :-). No filters, strange classes etc. especially
 comparing to similar wp_nav_menu. E.g. there is no class to parent LI (and
 it is often need to change e.g. for Bootstrap), nor any action or filter,
 the only way are some non-trivial preg_match on the full results or
 replacing the whole Walker, what is not optimal for forward and plugin
 compatibility
