stasek27: I have problem with the last (?) part of the quest - 'Defeat Dethmold's men'.
I kill all soldiers, and their boss Adam Pangratt in the underground corridors.
Pangratt lies unconscious, HUD shows red dot on the ground, but i can't hit him.
Dethmold just waits outside bluish force-field and there is no way to get to him.
Tried this part 3 times with the same result.

Now im basically stuck in the underground chamber, surrounded by forcefield, with Dethmold waiting outside of it. Any idea what to do next?

svetko: not using the X button worked for me, but i also just didn't attack him much..

i spared Pangratt at the end and he mentioned that he wouldn't need something and it looked like he gave it to me, but i didn't get anything.. bug?

vAddicatedGamer: Don't quite remember what he gave me. Probably some good throwing knives. There is a bug where sometimes the items you are supposed to get disappear i.e. do not show in the inventory.

Kitako: I had the problem too, and I solved it too avoiding to end the fight with a finisher (I was using heliotrope in that playthrough, if that helps).
