I'm not sure if this is intentional, but I don't think it's possible to have a bot automine. It gets screwed up because of the chance of metal ore or stone. You can either have a bot mine and then pick up as much stone as possible until its hands are full, but then it will miss all of the metal ore and it might get stuck because it has to be a multiple of 4 . You could mine/pick up 1 at a time, but then it will get stuck as soon as it reaches metal ore or vice versa. The linear way in which the bots work makes it impossible to give proper directions if the outcome of an action is uncertain. Maybe there could be advanced bots which can make multiple decisions based on logic you can give it. Maybe I'm just blind and can't see an obvious solution to this. I have only just started actually needing to mine, so maybe not having an autominer won't be a big deal, but I feel like that would be a welcome addition to the game. Great job so far guys, keep up the good work.
