Plain and simple
A wheelbarrow should not ( NOT ) be required if you want to place a stockpile inside of a Cart, Knarr, Wagon or anything with a liftable inventory slot
A wheelbarrow Should be required only for placing or removing a stockpile from an object with a liftable inventory slot.
I live on an island. If i plan on trading stockpiles of things i also need to plan on having a more wheelbarrows that one person should ever need.
its really flat on my island i kninda like it that way but i also kinda want to make my own volcano so i would like to be able to trade people for the dirt stockpiles they dont want. but currently i cant do this because the only way to get a stockpile into a knarr is to have it in a wheelbarrow and this is absolutely unacceptable.
it "should" work. take wheelbarow load a stockpile push it over to a cart wagon whatever and unload it and vise versa if you want to unload said object.
