Another oddity that has apparently gone long unnoticed, probably since it doesn't happen that often in practice.

In particular, check out clans.c, function do_drag( ), you'll find this section:

   nogo = FALSE;
   if( ( pexit = get_exit( ch->in_room, exit_dir ) ) == NULL )
      nogo = TRUE;
   else
      if( IS_SET( pexit->exit_info, EX_CLOSED )
          && ( !IS_AFFECTED( victim, AFF_PASS_DOOR ) || IS_SET( pexit->exit_info, EX_NOPASSDOOR ) ) )
      nogo = TRUE;
   if( nogo )
   {
      send_to_char( "There's no exit in that direction.\r\n", ch );
      return;
   }


It probably doesn't make much sense to only check if the victim can pass thru a closed exit, rather than checking the victim AND the ch doing the dragging, since at the end of do_drag( ), both will be moved there.

Fortunately the fix is easy:

    nogo = FALSE;
    if ((pexit = get_exit(ch->in_room, exit_dir)) == NULL )
      nogo = TRUE;
    else
    if ( IS_SET(pexit->exit_info, EX_CLOSED) 
    && ( !( IS_AFFECTED(ch, AFF_PASS_DOOR) && IS_AFFECTED( victim, AFF_PASS_DOOR ) )
    ||   IS_SET(pexit->exit_info, EX_NOPASSDOOR)) )
      nogo = TRUE;
    if ( nogo )
    {
    	send_to_char( "There's no exit in that direction.\r\n", ch );
    	return;
    }


That should fix it up. :cool:
