hi everyone i have expirienced a bug which is annoying me beyond all .... (can`t find a word to describe my anger ) . Ok now I'm @ Nar Shadaa my first planet after Telos and my intention was to forge my own light sabre . BUT i can't complete the Sidequest with the Hutt. Because i can`t enter a special area in the Docks . Its located near the lair of Vocca ,the walkthrough says that i have to overhear a conversation about kakh - hounds there to go on in the quest . The problem is the doors to this place, they doesn't exist means u can't do anything to them . PS sry about my language i'm not that good @ english
