Its it fear of my trap hall? All who seems to pass through those masterfully built halls of death unscathed seems so shook up they immediately scuttle their goods, im sure there's a good explanation for it like i've explained on my note. There's nothing immediately there to cause fear, no bodies, evil or disgusting rain, on the contrary my fortress has traps, catapults and rivers of alcohol (figuratively) but nobody wishes to stay, instead dropping everything forbidden in the same place each time. (if there's no consequence ill accept this exploit gladly, im ready to fight anybody off eitherway)

World is only slightly modded but nothing that should affect merchants this badly, elves and tributaries can use my multiple depots just fine, anybody travelling via a caravan freaks out.
