@geek: As
Huw said, the automated stock settings on your mining station are probably such that your idle haulers aren't needed at this point. Once you construct more mining stations, however, you'll them start moving material back & forth.
And no, you (thankfully) don't need to build a mining station at every asteroid, as they can handle material from multiple asteroids.
Some of us are huge fans of the first game and really didn't want to criticise DW2, but the issues are impossible to ignore and I couldn't in good conscience recommend it to anybody yet. However, knowing the developer as we do, I think we're all pretty sure it will be the game it can be in time.
This pretty much sums up my current feelings on DW2 as well -- both the good and the bad.
I can hardly believe I'm saying this, but I've pretty much set the game down for the time being. I'm keeping an eye on the patches/updates, but I suspect it's going to be at least a few months -- and very possibly longer -- before the game is at a point where I can really enjoy it. That it *will* get there, I don't doubt at all, but it's going to take some time.
