(Not a Bug - too bad): I had found a clever way to get rid of the Death Knights in the goblin mine, hoping to explore freely: I engaged them in combat (luring them with an archer) and chain-teleported them (with two mages) to the prison. Done. Except breaking off combat (by fleeing or moving away) instantly restore them to their normal position.
I was very disappointed with Larian there. 4th wall & world-sim breaking. :-((
