I actually got it working by doing:
1. Disable auto-leveling
2. Go to an innkeeper.
3. Add Hriavias to party
The above fixed it for me.
Furthermore: The bug in Brighthollow dissapeared as well.
Hello dear developer. It has soon been over two months and unfortunately I tried to recruit this sorry character and ended up with this bug. Dont have any earler saves.
What am I supposed to do?
