I've noticed the bot trying to get to close to the nodes.. It will run up to a tree and be running in to the tree jumping trying to get the node as if it was to far away still. I hit numpad 0 and it will continue to harvest at that point. Minning seems to be ok.
Stopping then starting the bot it quits jumping and harvests the node.
