Colossus Glitch, or Where are the Kryptonite Cannonballs?

[Hopi88]

Ive had experience with this to, I boarded a Colossus with a good crew but they all died somehow except me. Though I took only 1 or 2 out the last guy was in the back part of the hull. He was a low level officer so I tried using my sword on stairs and it worked only with the spinning thing attack. Though the time was like 5 sec. left I logged out. Later my friend told me to use grenades and I almost shot myself of being so stupid.
