It's kind of addicting and soothing at the time :smile: \n\nIt seems like AI does work fine with simple instruction but it gets buggy at some point and I don't really know what is the cause.\n\nHere are some thought of what could cause them : \n- I did test mine and ladder on single tile > it works fine\n- when selecting a range of tiles with mine or ladder, some workers seems to get stuck ? I'm not sure\n- when I order to mine an already mined tile, i think the worker will still go there and then get stuck? > not sure as well\n- when switching tabs on the web browser and then come back, some workers get stuck and no longer move > this one does seem to be consistent. (I'm on Firefox)\n\nBesides these, it's a great game !
