I'll add this here so you can put this on the checklist to implement.

Add waypoints for NPCs so they return to their original standing position. Sometimes when a hostile faction is spawned at NPC areas, the merchants and questgivers run to battle and don't go back to their spot.

Also, the ... that are praying can be 'talked' (they respond to your mouseclicks) to and they stand up permanantly. Perhaps make them ignore your mouseclicks or get them to return to their original positions after standing up.
