In #61 transport pipes were added. The issues original description references being able to connect the output of a barn to in the input of a shed. I tried to do something similar (connecting a chest to a shed using a connecting path). That isn't working for me and I don't know why.

What I'm trying to do:
I added "Cobblestone Path" to the list of Connectors
I'm using that Cobblestone path to connect a Large Shed filled with casks to a chest.
I also connect that chest with another (Small) shed filled with Kegs.

Now I almost think it isn't the fault of the core game because of how Barns behave differently that Sheds. With a Barn, I can make a Cobblestone Path occupy the square inside the barn that immediately leads outside. In the Shed I can't seem to place a path in that respective square.

So maybe this doesn't work because the circuit can't be completed?

Transport pipes aren't implemented yet. (You're probably thinking of connectors, a much simpler feature which also extends connections.)
