So I'm pretty new to this game for starters, so bear with me. I hired some miners and had them doing their thing at one of the mines and logged off for the night. The next time I got on, I had a message saying I received 33 pcs of coal. Does anyone have any idea of where this would be located? I looked in all my backpack menus and could not find them. Do I need to be online at the time to receive the items? If this is stated somewhere else I apologises but I could not find it.
