Ok, As I was in the GFS Valhalla,The last room with the pirate code. An Invisible Thing started to attack me, I switched on the x-ray visor... Nothing... But, i got a lock on it with luck and a quick eye(the arrows that show whare to point the crosshair before locking on was moveing fast), and the Panel that shows weak spots showed up, and thare was still nothing, It was moveing around the room in lightspeed, Or it seemed that fast. It died when i started to fire wildly, any one expeareance this before?(no joke, if you think its a joke i will think less of you.)
