Again, I see many people (including me) had the very same problem.
It seems it should be corrected in journal and coding.
First, in quest Lizard's Treasure at one point you have to talk to witch in regards to getting the information about mind-control protection.
You HAVE TO initially agree to her terms to hear her out. BOTH of them, BOTH day and night one. After the meditation and "Don't worry, you'll know" (that she will keep an eye on you - hence the crow) AND proposition to create amulet to block mind-control you will get an option to actually create it (to be sure make a save - just in case). AFTER all this next quest with nameless will progress.
Nameless will be NOT pleased if you protect against him and will be pleased if you refuse in the end what witch have to offer. Your choice.
If you don't get the rather obvious prompt after "slept until morning" that there was a crow, then you don't meet the requirements.
The requirement being ALL parts of Lizard's treasure quest done. Without that part you WILL NOT progress.
I hope that helps, if not, let me know, we will try to figure it out.
