I am not sure this is a bug, but it feels like one.
It seems like every time I load my save games, everyone dropped what they were carrying when the save was created. I understand that the game may no longer knows what that villager/wagon was doing or why they were carrying that item, but having all of these items laying around is… odd. Eventually people pick them all up, but there has to be some method of preventing or auto-storing those items if the villager doesn’t have a reason to be carrying them anymore.
This was a big problem in earlier versions, mostly fixed, I think, dropped items will be picked up when needed, such as stone for buildings, vegetables for food, almost anything being stocked in the Trading Post.
Villagers still drop everything after closing the game, so items they were carrying when you save and close start on the floor ad the villagers just walk away.
They also drop items if they are moved manually or but he game into a different profession, instead of completing whatever their task was.
Still early access i know, but would be good to know it is in the pipeline?
