I just experienced this same problem. The ship I\'ve been building for the past 4 days had always worked fine, up untill today when I finally finished it. Now this problem occours. The shape of the ship has scarcely changed, most of the work was being done filling interior spaces with more power and what-not. I have tried to move to an empty section of space, even zoomed out to verify that I\'m not actually colliding with anything.
Also, noticed a bit of an anomoly, my crosshair seems to spiral around the targeting reticule when I try to roll, something that never happened before.
