Missing NPC or bad scripting

Desolace 40.4/79.4, two issues:

1) The super seller vendor mechanical bot has parked there and has not moved since easily 12 hours now. It should be taking its usual route along with its accompanying 'masters'

2) said masters (Gizelton Caravan goblins) make a stop there:
a) for a few minutes, and ONLY on their way up north. So it's not twice per "route"
b) only when the entire caravan arrives there AND in one piece. As you may recall, there is the relevant escort quest one may undertake in regards to this. Left on their own devices, it is possible they will not manage to arrive, at which case a player would have had to wait for the lot to respawn at starting location, -and- wait for them to once again, get there
