Due the current times i think it would be apropiate to move her to fm, i mean shes part of risk population and what maya has start to look really sus..
I think it would be fair to leave them where they are, because these NPCs have a storyline that makes sense for them to stay in those maps. And being that also it's an old school gms server, it would make sense to do all that travel to see her. Besides, we got fast travel tickets and tp rocks to make travelling less longer.
I've made a suggestion that majority of the event NPC's be moved to the lounge. I think it's a great easily accessible area that doesn't cause overcrowding in the central market. I think putting NPC's in the free market or town central location is out of the way for majority of their uses.
