So this is what I'm look for: - Automated vertical flying machine that will go up and down - Must move a 2x2 area to the max height on a residence or to the height it can achieve based on what was just moved (e.g. if it moves 4 trees to the top of a residence, the next time trees are grown on that 2x2 area, those trees will move/stack just below the last set) Pay is negotiable. PM me for details.
