SPOILERS present in this topic
I finished the part where "I spoke to ruin in a dream" and now every time I go to sleep I get the dialog "you are awoken by the noise of footsteps". Unfortunately the ShadowScale assassin never comes for me, so I'm stuck with no HUD and no movement forever.
details:

• I am often getting the message "you cannot sleep with enemies nearby". I originally thought this was the problem, but no longer.
  
• I consoled "save test 1" and opened the resulting save info file. There is no mention of a Master Shadow Scale Assassin anywhere, regardless of what I put in the search bar, but Smells of Death can be found in two places in the file (first place seems to detail position, the second tells of stats). This seems odd to me because the Master Assassin and Smells of Death are supposed to load in the same cell according to the construction set.

Can anyone tell me what to do? I would really like to force the mod to try loading the Master Assassin to the DummyCell again, but I'm not sure how to do that, or if the assassin would be attached to his relevant script when he loads.

Which version of RTT are you running? You could enable your controls by typing "enableplayercontrols" into the console, and at least you'd be able to locate the assassin. I've had this bug a few times (v.2.5) when sleeping in an inn, and the assassin would not be on my floor, or he'd be outside the door, etc. In my case, the above solved the problem for me. IIRC, saving a text file doesn't always show every piece of data, so he may in fact be there somewhere.

If that doesn't help, I would suggest posting your load order. Someone might be able to spot something.

Good luck!
