For the record I have also unsubbed.

I am having the exact same problem right now. A youtube video shows what I am experiance with my IA sniper. However I can't afford to loose anymore credits on repairs. Four attempts and my wallet is beginning to get hurt. I can't proceed until it is fixed. So far this seems to be the end of my IA adventure at lvl 34. I have petitioned it twice and got the same impersonal droid reply. These droid replies are really frustrating, and seems like no one is actually reading them. Seeing that it has been a week since this has been reported, I am really disappointed that the bug is still not fixed, as it is breaking bug as characters can't proceed.
