For me and some others it is bugged: Thralls walking through walls and doors and being killed
For some it is NOT and you have to set the right behavior - even when there is NO right behavior, as even on “stand and guard” this idiots are teleporting around.
Even dancers on “no attack” are teleporting around.
My archers who ported were on: Triangle foundation or triangle ceiling pieces. One was at a normal foundation and ported herself into spikes, which slowly killed her.
