Here is my logfile.
I started the game and apart from moving and opening doors, did only the following:
tried to use shallow grave ritual once (error: too far away)
tried to use circle of power ritual once (error: too far away)
tried to ignite transportory stone once; (error: too far away)
Ordered a thrall thats sunk into the floor to follow me (doesnt move)
Tried to order that thrall to move couple times (error: cannot reach that location)
Then tried to “place and guard” that thrall (error: must be placed on walkable floor)
Ordered the thrall to stop following and then shut the game.
