I really enjoy the Ambient NPC system, and feel like it's a great addition to EfU. I feel, however, that perhaps when the server has been up for many hours, that just too many of them cluster up in one spot. I suggest that Ambient NPCs despawn after a set time (probably random), to emulate coming and going.. That way, if you are trying to get back to hear Drezdles new joke, maybe he already left and you don't get a damn thing for being late to the party.
Thoughts?
The joke-gnome was clustered in the center there too. They do seem to be spread out-ish though, so maybe no bug.
