I have asked many times for a pet/robot of some kind that can extract my claims for me.
Maybe a (L) crafted robot. As well as usual excavation decay, it would require oil to operate. Also it should agro mobs just as we do, so it should have armour and decay.
Or Maybe our currently useless pets could be trained to use our excavators.
Also I would be quite happy to pay a small, reasonable fee for a premium feature such as this, from the webshop.
