So this has happened to me twice in a row after the latest hotfix, and never happened to me in dozens of playthroughs before: when freeing Nere, one of the Duergar will walk back too soon, walk over the fire, and aggro the whole area, even the other Duergar I had convinced to help me. This makes the fight quite a lot more difficult. Is this just my bad luck, or has this been indeed introduced with the hotfix? Thanks.
