I'm having a similar problem. Atton and Keira are standing by the door before I talk to the hand maidens. I can go about and talk to T3, the spiked head guy is laying on the floor in a force cage, and Keira will not talk to me (standing by the door). If I try and talk to Atton I get "1. Cheat Node: Continue conversation with Kreia" or "2. Cheat Node: Jump to PC conflict with Atris" Having allready talked to Atris, that doesn't really do anything other than restart the conversation.
So I can talk to T3, but not Spikes, Atton, or Kreia. Is there anything I can put in the console to jump ahead to the next cutscene or something? I really can't do anything to move the story forward other than fight the Hand Maidens
