That may be true, but it's something else as well.

npcspawn only seems to work "part of the time" -- sometimes the new mob gets added or created, sometimes not.

For instance, say I create 10 new mobs, I zone out, only 3 may be there when I zone back. It seems random.

Add, same thing. Say I add 20 mobs based off of a dbspawn, when I zone back after the zone shutdown, not all will be there. Sometimes 1 or 2.
