A Minecraft Fabric mod that extends Wandering Traders to trade you back lost items
This Minecraft mod that takes the Wandering Trader concept from one of SimplySarc's suggestion videos and implements it.
Whenever a player dropped item despawns/gets destroyed, the stacks get internally added to a list and have a chance to show up next time when trading with a Wandering Trader.
Of course, you can legitimately trade your items back only once (we don't talk about villager trade glitches ^^)
