Summary0000466: Multiple trade depots cause the merchants/traders to behave oddly
DescriptionIf you have two depots and only one is accessible the traders don't move from the edge of the map.

Deconstructing and/or forbidding the inaccessible depot causes the traders to start moving to the depot that has been accessible the entire time.
Steps To ReproduceBuild two depots, make one inaccessible, wait.
Additional InformationA wild grizzly bear came up and drank all the booze the elf traders were carrying, they didn't try to run away and/or fight, nor did the Grizzly Bear attack them after finishing off the booze.

Would elves normally run away from a wild Grizzly Bear? Seems like not only were they not moving towards the accessible depot, they were also prevented from taking any actions whatsoever.

Had two separate trade depots, forgot to destroy the old one. Elves went to the new depot, but all their goods went to the second.

Traders have no real ownership over their goods

This bug is still present in 47.04, more accessible since tribute demands is able to update the awareness of civs migrating within range in vanilla DF to send parallel caravans of the same race between different civs & modding overlapping active seasons.

Traders will crash into each other's caravans at any stage of the process trying to access the same depot even to bump into the back of and deconstruct the one that is unloading without waiting or pathing into alternative trading depots.

Extension of 0005687's behaviour.

Save here from 44.12 gathered in retrospect consideration specifically towards caravans versus pack-animal behaviour, speaking from anecdotal experience of instances where i've had to start from a fresh backup-save because of this problem i haven't had anything fresher to show, so my apologies.
