Can someone clarify for me what the "Container" is that is tested for being empty here? I don't thing it is a "Storage Container" because if it was, I think there would have to be a question mark ? that we could click onto to identify which "Storage Container". I don't think it is a "Crude Backpack" because the Backpack only really works when it is in the "Upgrade" slot for the Farmer, and it cannot be added to the "Upgrade" slot of the bots.
