It seems I messed up the directions a bit...hmm...well not exactly, but the thing I have you searching for in showthread.php actually appears twice, and it needs to go in the second place, not the first.

So here goes:
In showthread.php, find

PHP Code:

    $postdone[$post[postid]]=1;
  } 


and add right below it

PHP Code:

  if ($post[hidden]==1) {
      $hidden=1;
  } else {
      $hidden=0;
  } 


It should now work. I've updated the installer with this change.
