1. Script Name:
Resume Walking Waypoints After Conversation

2. What it does:
Makes an NPC resume walking waypoints after a conversation.

all you really have to do is this:

In every conversation there is a tab in the editor in the lower-right quadrant labeled 'Current File' and in this tab there are two boxes, one labeled 'Normal' and another called 'Aborted'. Just put the following reference into a built-in script into each of the boxes:

nw_d2_walkways

That's it.
