This is a Basic guide for the new guys that have just started with there new server.
First of all start your server as usual.
login, Spawn the NPC you want to set waypoint(s) to.
Target the npc. And remember to stand a bit away for the target so it wont look odd.

Now write this command to Spawn the NPC.
.npc add entryID

You can find the GUID id, by typing in this command.
.npc info



Long waypoints need that the npc is following you...
.npc follow

And this command to add Waypoint. Move to the location you wish the NPC to move to.
.wp add GUID

You can use this command as many times as you like in different Locations.

When you're done adding Waypoints, simply write.
.wp load GUID

Sometimes you might have to restart the server to make it accually work.
