If a mining drill is apparently applied to a non-pointable node, do nothing rather than drilling as normal. This situation usually arises from lag, where the news of a node having been drilled didn't reach the user quickly enough and the user thereby applied the drill twice to the same node. The second drill attempt would formerly consume charge and then find that all the nodes it wanted to dig had already been removed.
