There is a known issue in the download version of the game where certain NPCs can be hostile. This can be fixed by editing their names in the data.000 file (usually if the imp in the inn is hostile the council member is, as well, and a couple NPCs in the wastelands). This can be done manually in a hex editor, or by using a program created by Jem in the Steam discussion
Imp Council Member. Or you can zip the data.000 file in the save folder and email it to me (raze@larian.com).
