not sure, They were working just fine when I added them in almost 3 months ago, but a lot has changed since then it was probably broken :/

What did you do to get the original 4 to zone to the appropriate docks?
I've been working on my moving npc DB and noticed alot more boats that I would like to get working too.
I have tried to find the zone points , but can't seem to figure out how you set it up.
Any insight as to how I would go about it would be greatly appreciated.

I wrote the code in that would force a client to zone to the right zone if they were on board the ship and they crossed an particular area in the zone.

lol can you share the code with us lol :)

its part of 4.4

Does the code work for all the ships?
And does the ship have to cross the zone at a particular point?

Its hard coded to use grids 1-4 but any npc should work as long as they use those grids.
