I guess with all the talk on issues Im not the only one having lag save problems. I also have a glitch with companions after I killed the witches farkas talks with me anthen wants to go kill the last siver hand but the game does not give quest to activate it so all of my companions just stand around or wine n cry n farkas does not even remention going anymore just the one time. I see this problem with others if you back out of a quest conversation after one has started you loose the chance to start it. I just messed up and saved after our talk and now there is not a quest. They need to fix all npc encounters to respawn conversations if quest is not activated.
Please feel free to post other ps problems or glitches.
