Strangley this same thing happened to me and I was on the xbox version. reloading earlier saves from the planet didnt work, I had to load up one from Telos (wich wasnt so bad since Nar Shadda was the first planet I did this time round) Im wondering what caused this glitch to happen, I've played through this game like 6 times and this never happened before. Also I've looked around this and some other sits and never heard of this happening to anyone else for the Xbox version. So does anyone know what causes this glitch, and has anyone else had this happen to them for the xbox version?
