I've noticed this a lot, sometimes NPCs will stay behind, if there are lights effects that are removed, sometimes other NPCs will take on their light effect, sometimes new NPCs just won't show up, ...

This mostly happens with GMAPs (but not always); to properly add stuff to Era's GMAP, often we have to update the GMAP, restart the NPC-server, and reconnect everyone. It's ridiculous, hence why normally when we add NPCs we use putnpc2, even for permanent stuff.
