For example, how do I replenish a used-up supply wagon? I tried taking some to a rear-area home city, which had loads of supply, but they still seemed to stay empty. How can ships be used to provide supply, I know transports can be used for this purpose, but its not clear to me how? I can't seem to create depots with (2) supply wagons or (2) transports - do they need to be full? What else might prevent me from creating a depot? Any more tips about how supply works would be gratefully received! Thanks
