reset.c, do_reset

in the "random" part find

      if( ch->in_room->first_reset->prev )
         ch->in_room->first_reset->prev = pReset;

change it to

         ch->in_room->first_reset->prev = pReset;

in the "trap" "obj" part find

         if( pReset->first_reset->prev_reset )
            pReset->first_reset->prev_reset = tReset;

change it to

         if( pReset->first_reset )
            pReset->first_reset->prev_reset = tReset;

find

         if( ch->in_room->first_reset->prev )
            ch->in_room->first_reset->prev = tReset;

change it to

         if( ch->in_room->first_reset )

in the "hide" part find

         if( pReset->first_reset->prev_reset )
            pReset->first_reset->prev_reset = tReset;

            pReset->first_reset->prev_reset = tReset;

find

         if( ch->in_room->first_reset->prev )
            ch->in_room->first_reset->prev = tReset;

change it to

            ch->in_room->first_reset->prev = tReset;

Remcon said:

This fixes crashing issues found caused by first_reset being NULL when adding in new resets.

I'll just let Remcon's fix speak for itself.
