Now, some of the database are actually using the Nektulos.eqg file, so this makes a new delema; what database uses/or doesn't use Nektulos.eqg? 
if you are a client logging into the peq server; 
- you should have posted this question in the peq forums 

  but I think you need the Nektulos.eqg file in place
- if you have your own server and it's a newer peq version;
- you should have posted this question in the peq forums 

  you probably need the new map files for the Nektulos.eqg, although I don't see how      this would make you go underground , there's more to it. like zone points, etc.
 
my unwanted opinion;  
probably should have left Nektulos as it was; worked fine, everyone knew what they had to do, and it avoided more confusion.
