To reproduce, connect a double chest containing 64 cobblestone using two cable blocks to a storage network. The network will claim to have 128 cobblestone in it.

Maybe shift left+click to open a GUI that let's you disable north,south,west,east, up,down. just like EnderIO item conduit pipes. though you had to have a wrench to do that.

YEP! good catch. I was hoping nobody would notice this....

You dont even need a double chest, you can use a single 1x1 chest and just but a connection cable on 2/3/4 sides

Eventually i want to do a big refactor and use Item Capabilities more heavily, and then hope that fixes everything....., but thats a lot of work and has potential to break the (seemingly fragile) current state of things.

Luckily it cant be exploited, as if you click on the 128 you get 64 and then its gone.

Maybe i can do some sort of check on cable placement to check bad locations and block it.
