So I've seen demos in-game of a few decent drone miners. Having a problem with mine though; they mine fine, but I've made 5 prototypes from scratch, 1 has terrible aim but very slowly (with less than 5% of its beams hitting) will mine a field, one refused to mine at all in fleet though it works when piloted, the other 3 ALL have the same problem. They mine roids just fine, but every time they finish one roid, they start spinning and just do that forever until issued new orders. Any insight into keeping drone miners from pulling this spinning crap?
