2 different (propably unrelated) bugs accured during the final bossfight against lucian and the others:

1. no matter what i do or in which order i defeat them, adramahlik doesn't show up during or after the battle, even though i did the deal with him in "doctors orders"

2.if i talk braccus rex out of fighting me (beat down dallis, then using the speech-option with the villian-tag and passing the 3 following speech-checks), the fight doesn't end even if i kill everyone. my own characters will simply alternate turns till eternity.
