Ah, I made the assumption when I just saw the one box, my bad!
I tried running the master/worker thing today and the worker was fine but the master kept not accepting trades or frequently cancelling the trade window or coming to a halt after accepting the essence and not using it on the altar. Could we also get an option for whether we want the master account to also make trips to and from the bank or whether we want it to just sit at the altar and wait for trades?
Walker 1 had a lot of issues with the earth altar, kept trying to chop a tree in the way of the ruins on its way there, I didn't try any other walkers
