in skills.c function do_sset
find
         CREATE( aff, SMAUG_AFF, 1 );
         if( !str_cmp( duration, "0" ) )
            duration[0] = '\0';
         if( !str_cmp( modifier, "0" ) )
            modifier[0] = '\0';
         if( ( loc % REVERSE_APPLY ) == APPLY_EXT_AFFECT )
         {
            int modval = get_flag( modifier, a_flags, AFF_MAX );

            if( modval < 0 || modval >= AFF_MAX )
            {

            snprintf( modifier, sizeof( modifier ), "%d", modval );
         }
         else if( ( loc % REVERSE_APPLY ) == APPLY_RESISTANT
         || ( loc % REVERSE_APPLY ) == APPLY_IMMUNE
         || ( loc % REVERSE_APPLY ) == APPLY_SUSCEPTIBLE
         || ( loc % REVERSE_APPLY ) == APPLY_ABSORB )
         {
            int modval = get_flag( modifier, ris_flags, RIS_MAX );

            if( modval < 0 || modval >= RIS_MAX )
            {
               modval = 0;
               ch_printf( ch, "Unknown resistant/immune/susceptible/absorb: %s.\r\n", modifier );

         }
         if( ( loc % REVERSE_APPLY ) >= APPLY_STRIPSN && ( loc % REVERSE_APPLY ) < APPLY_STAT )
            if( duration == NULL || duration[0] == '\0' )
               snprintf( duration, sizeof( duration ), "%d", 0 );
         aff->duration = STRALLOC( duration );

change it to
         if( !str_cmp( duration, "0" ) )
            duration[0] = '\0';
         if( !str_cmp( modifier, "0" ) )
            modifier[0] = '\0';
         if( ( loc % REVERSE_APPLY ) == APPLY_EXT_AFFECT )
         {
            int modval = get_flag( modifier, a_flags, AFF_MAX );

            if( modval < 0 || modval >= AFF_MAX )
            {
               modval = 0;
               ch_printf( ch, "Unknown affect: %s.\r\n", modifier );
               return;
            }
            snprintf( modifier, sizeof( modifier ), "%d", modval );
         }
         else if( ( loc % REVERSE_APPLY ) == APPLY_RESISTANT
         || ( loc % REVERSE_APPLY ) == APPLY_IMMUNE
         || ( loc % REVERSE_APPLY ) == APPLY_SUSCEPTIBLE
         || ( loc % REVERSE_APPLY ) == APPLY_ABSORB )
         {
            int modval = get_flag( modifier, ris_flags, RIS_MAX );

            if( modval < 0 || modval >= RIS_MAX )
            {
               modval = 0;
               ch_printf( ch, "Unknown resistant/immune/susceptible/absorb: %s.\r\n", modifier );
               return;
            }
            snprintf( modifier, sizeof( modifier ), "%d", modval );
         }
         if( ( loc % REVERSE_APPLY ) >= APPLY_STRIPSN && ( loc % REVERSE_APPLY ) < APPLY_STAT )
            if( duration == NULL || duration[0] == '\0' )
               snprintf( duration, sizeof( duration ), "%d", 0 );
         if( ( loc % REVERSE_APPLY ) == APPLY_WAITSTATE && ( modifier == NULL || modifier[0] == '\0' ) )
         {
            send_to_char( "You can't affect waitsate by nothing.\r\n", ch );
            return;
         }
         CREATE( aff, SMAUG_AFF, 1 );
         aff->duration = STRALLOC( duration );

It was creating the affects even if returned and never freeing them (could lead to crashes or odd behavior).
If you did like 'sset <sn> affect waitstate' it would crash on saving/viewing/using the spell/skill.
