To do that you must rebuild map_cache for that..
if you just disable it via maps_athena.conf it will make your char got crash when going into the disable map.
to change that , you would need to hexedit it
use any hex editor >> i would suggest HxD
Search for the job name and change it the client would work fine but you would need to do that every time you make a new client

It causes random crashes after map loading for new EXEs. I fixed it. You can add it to your fork of NEMO.
