Smith the Horse in the Dream Realm has the same character portrait as the dead ghosts encountered in the game.
I am using the latest versions of Exult and the SI Fixes mod.
Attached is the best savegame. All that's needed to replicate the bug is to walk to Rabindrinath's and talk to Smith.
This is a general bug in Exult it seems. Attached is a screenshot of the original, not showing any portrait.
The bug is in the Usecode that calls the Guardian's face. Exult uses the face of the Ghost because that's the same as the NPC number. As posted in the phorum thread, it is possible to see the Guardian's face with any other nightmare talking.
I hope we do not use a blanket fix for this, since I want to use say with no face to match the U6 style intro in a longer cutscene; that is text below, centered.
