Hi
Yes, the caravan should actually set off on its own like the other caravans in this area.
The caravan in the direction of the front camp also keeps setting off on its own.
And you play the event by protecting this caravan.
For the one that has been broken for a while, you protect the caravan from the corpses.
On this entire route, the enchanted zombie who can have a map only appears once.
You can't trigger the caravan to start moving, it has always done that on its own.
Greetings Felline
