Lurker_005: don't worry about the destination: zone, x, y, z
I've completed all of that already and the POK and all POKTELE500 doors will port you within millimeters of your destination door. I have not included "dest_heading" as you'll notice it is still "0".
Hope it helps out.

I know its not as nice looking as yours but it is in the same order anyhow =)
Everyone will have to drop their doors table manually unless you care to fix this part I'm more of a Systems/Networking Guru and only an enthusiast of Programming =)
