Ok, I haven't been able to find anything like what I'm seeing, so I'm going to ask here.  Forgive me if I missed it with the search. 
I've got my zones set to save state.  With them like this, a lot of times the zones only have partial spawns in them.  I have to #repop them to get them to have a full spawn.  For example, Plane of Knowledge only had 59 NPCs in it until I repopped it.  After, it was fine (305).
So...  Is there something I'm missing?  It seems to work better when I clear out the zone_state_dump table, but is that necessary every time a server is rebooted?  It'd really suck if so, but I can deal with that as long as I know.
Thanks!
