Yes, there was a bug with automated caravans that caused their routes to be set as empty. I found the cause and fixed it in the code, but that still left a bunch of caravans with no idea where they were supposed to be going.
I fixed it the quick and dirty way, by telling them, "Well, you go straight from where you started out to your destination, then back again"
