Bug: Extra descriptions are not linking to their targets
Danger: Medium - Data loss during OLC.
Discovered in: AFKMud 2.0
Found by: Lazerous
Fixed by: Samson

mud.h
Locate:

template< class N > extra_descr_data *set_extra_descr( N *target, string name )


Replace that entire template with this:
template< class N > extra_descr_data *set_extra_descr( N *target, string name )
{
   extra_descr_data *desc = NULL;
   list<extra_descr_data*>::iterator ied;

   for( ied = target->extradesc.begin(); ied != target->extradesc.end(); ++ied )
   {
      extra_descr_data *ed = *ied;

      if( ed->keyword.find( name ) != string::npos )
      {
         desc = ed;
         break;
      }
   }

   if( !desc )
   {
      desc = new extra_descr_data;
      desc->keyword = name;
      target->extradesc.push_back( desc );
      ++top_ed;
   }
   return desc;
}


The main problem in the template was that when an extra description was created, it was never being linked to the target. So an index object, instance object, or room which had one added would just toss away memory into the deep black void. This also has a bit of neatness cleanup as well.
