Just one problem that I've foiund, but not sure if you corrected in this version... skeletons and decaying skeletons are dropping bone chips, but they are magical and non-stackable.  I believe the correct item number they should be dropping is 13073 (or 13703...13730?) or something like that.  I'm at work right now so I can't check, but I think that's it.
So if I change the skeleton bone chip drops can it still affect all of them globally?  I know you said things are done on a per zone basis, but to replace bone chips on a per zone basis would...well...suck.  
Once again, thanks for these tables.  HUGE help!
