No, same problem here.
Actually got "Hack" to give me the Gogas Afadin part before I got to the part requiring him on the main Heritage Quest.
Evil toon, hadn't done Ghoulbane. Went into Nek, Gogas won't say diddly, no quest update. Sooo...
Deleted the Gogas quest and went back to Somborn to see if I could clear the bug. Now I can't even get the quest from "Hack". Already have the Blackwater Mask, too. He just stands there and asks if I got the Mask yet.
/em smacks "Hack" upside his big fat head.
So, I'm doing Ghoulbane (at 73) to see if that advances things any.
