The functionality of Mag has been changed considerably. It seems to pull purpendicular until there's a straight line path and then it will pull towards the beacon. So basically the path looks like an L instead of a straight line. I don't think this is intentional, but could be mistaken.

Well, at the moment if there are two hexes that closer to beacon it checks both and first it check hex that goes first clockwise. It looked not so bad when I just implemented it, but I'll make it a bit more accurate soon.
