The problem is that your x,y,z coords are incorrect in your db; the code looks up the target coords when you go to zone, to see zonepoint the client is using. Changing these will only zorch your zonepoints table and cause the server to send you somewhere either undesireable or back into the same zone you were just in.
This will be fixed in upcoming MWnpcmov db's. For now, just sit tight.. Maybe adding this info to your #motd will alert people on your server to be cautious of using zonepoints until you update your db. I dunno
Be careful
