Farmer
I have a combo like this on Ginger island (with Automaton mod) and occasionally I've found Oak resin or Pine tar from the chest in the middle. Nice, but where does that come from? Oak resin, Maple syrup, salmonberries or blackberries sometimes end up in certain chest on the main farm, but that is understandable -- there is a touching chain. The only connection could be the mailbox, but it has no connection on the main farm (and a) no-one sends just those products b) mail attachments are not acting weird, they come with the letters)
