I decided to defend the merchant Verzano, and after killing Danna party i only get exceptional negative reputation with them but the quest don't progress.

I talk to Verzano and his text is as if i didn't even delivered the package yet :/

I think you aren't supposed to save him

#Just let him die and problem solved I've chosen to kill him personally, that way you avoid the huge negative reputation

Yep, the devs are aware of this bug and working on it
