I seem to have encountered a previously unseen breed of the Telos bug, in which the PC is imprisoned on the Telos academy. My situation is similar to this, with some differences:

 

• When I enter the academy, no matter what dialogue options I choose, the "Give us your weapons" conversation ends with a black screen.
  
• Saving the game and loading that save game fixes the black screen problem. It spawns me near Atris' chamber, with Atris standing outside.
  
• I have to go up to Atris and talk to her to trigger the pre-set conversation.
  
• Everything proceeds as normal, Handmaidens escort me away, etc.
  
• At this point none of the Handmaidens except Brianna talk to me. No other NPC's will engage in conversation with me except T3 and Brianna.
  
• The pre-set conversations with Kreia, Atton and Bao-Dur do not trigger. The one with T3 does trigger, but it is as if starting a conversation with him on the Ebon Hawk. All of them are in their cages and don't move from there.
  
• Worst of all, the Ebon Hawk is unable to be entered. Nothing happens when I run into the ramp.
  

 

I am certain this is not a previously-encountered bug, so it warrants its own thread. How can I fix it, or at least force the game to trigger the proper ways? Is there a command that will just teleport me straight into the Ebon Hawk?

After extensive googling I found the problem. It's the result of a mod. It can be fixed by deleting 262TEL.mod from the Modules folder.
