Right you are, @BarakIII .
So, there’s something I noticed when spawning thralls on single player that might have something to do with what you experience.
Pre AoW, as soon as you selected the thrall from your shortcut wheel (bar on pc), you would see the features even before actually placing it.
Now, something has changed. You need to place them in the world AND take off a piece of their clothes for their features to show. I noticed the mouth, hairstyle and color and the brows’ shape remain constant. A long time ago we had a similar situation. Then it got solved.
If you pick up the thrall to move it, he reverts back to his pre placement features until you place him.
