I read somewhere they should have been fixed, but in my latest game I recruited Vatnir and told the Harbingers to go home because their work was finished. The ending slides were the ones where Hafjorn leads them into being a fanatical sect and Vatnir didn't get mentioned at all.
Not entirely fixed then?
This one is kind of interesting and more just a minor nuisance. Every time I click Continue on my game Vatnir is moved to the far right party position. I usually keep him in the middle slot, but every startup, there he is again in the far right.
