Sorry, i got a little bit of factorio PTSD;
All the Storage Crates of the same type having shared contents (Ex 5 of boxes of planks sharing the same item pool - multiple SCP-216 intensifies), and on my humble opinion, once (IF) it is changed, the bots will go on strike for delivering from box A to B 4ever.
Being that so, arms and conveyor belts (with the bots being able to be set to pick from belts - like Fordism!)
Please destroy this idea, help it or love it
With love, for this awesome game,
