Yeah, I am having a lot of trouble with this right now. I get trapped against sand dunes, walls and stairs. Often with my thrall working in concert with my horse (they hate me). Some times ducking helps me out or ordering thrall away. The last resort is to remove bracelet as I cannot get out. I thought the horse and thrall were adjusted to keep a little more distance, but I guess that leads to them blocking doorways.
Oh I’m lucky I haven’t had to remove bracelet yet.
Usually after some swearing about the stupid horse I can duck or I have to use the katana dash attack
