I really know nothing about scripting but here is what Ziu said (not sure if it will fix your problem tho):
Tanto en este script como en el de glast heim al final tienes la edición del src para implementar el comando playertalk (necesario desde hace varios meses para cualquier memorial/instance o npc)
"In the Sara's Memories and Old Glast Heim scripts, at the end, you have the src edition to implement the playertalk command (needed since months ago to any instance/memorial or npc)
El problema del NPC con la id 10007 esque para rAthena cualquier ID superior a 1001 es considerado una MOB por lo tanto tienes muchas opciones para poder lanzar ese sprite. Modificar el SRC (the one I have has some problem with the mobs).
"The problem with the NPC of the id 10007 is that to rAthena, any ID over 1001 is considered a MOB, so you have many options to launch this sprite. Modify the SRC (the one I have has some problem with the mobs).
Editar tu client-side y añadir el npc portal con otra ID modificando los lubs... etc etc etc..
"Edit your client-side and add the npc portal with other ID, modifying the lubs... etc etc etc..
Como tú comprenderás tengo que poner en el script la ID oficial del NPC no puedo ''customizarlo'' a no ser que fuera algo superior y necesario... elige la mejor forma que se adapte a tus necesidades.
"You must comprehend that I have to put the official ID of the NPC on the script, I can't customize it unless it's really necessary. Choose the best way for you that fits your needs"
