Caravans & Convoys - Automatic Trade

Caravans & Convoys - Automatic Trade
Version 1.0.10  |  Minecraft 1.21.1, NeoForge

A duplication bug is gone, and the wagon no longer takes your own horse.

FIXED: trades could copy your best item

When a dock loaded a trade, it lumped everything it took from the chest into one pile that carried the details of the first item it found. Items that look the same but are not, such as enchanted books with different enchantments, damaged or enchanted tools, named items or spell scrolls, all arrived as copies of that first one. Two docks owned by the same player could turn a chest of junk books into a chest of their best book.

Every item now travels as itself. A load of a Mending book, a Sharpness V book and a Protection IV book arrives as exactly those three books. We ran that very trade on a test server: the old version delivered three Sharpness V books, this one delivers the three originals.

FIXED: goods lost when a load did not fit

A trade too large for the wagon bed used to be loaded anyway, and whatever spilled over the top simply vanished. A dock now only sends a trade that fits the wagon as real stacks, and anything that still does not fit is kept on the driver instead of being thrown away. If the chest turns out to hold less than it promised, the trade is called off and everything goes back where it came from.

FIXED: the wagon could hitch a player's horse

When another mod swaps out a draft horse (DragN's Livestock Overhaul does this), the dock adopts the horse that takes its place. A tamed horse that had just loaded nearby looked exactly the same, so a player's own horse stabled beside a dock could be hitched to a caravan. Horses with an owner are now always left alone.

FIXED: stray horses after a failed launch

If a wagon was placed but its driver could not be created, the two draft horses were left standing in the world. They are now removed along with the wagon.

Thanks to Xmat5, who found all four.

Existing worlds
Drop in over 1.0.9. No config or network changes, so the server and clients do not have to update together. A caravan already on the road when you update finishes its trip normally.
