I'll see if I have an "uncorrupted" savegame left ...

One thing did happen: Because there was some trouble with the quicksave option, I quickloaded and the game opened a quicksave from ages ago, trying to multiply the healing gem back in healer-town. Luckily I had a real savegame that could take me back to where I really was, but I think since then the shroud was gone.

I have seen the boar, and I got that quest, but I hadn't been to Boratus' house before though it was unshrouded on the map.

I didn't trigger the councilmemberquests because there were no crystal balls in the Meeting Hall. None at all. I had been there though, but I hadn't saved and got killed by the Succubus. My savegame took me back to Rivertown, and I decided not to go to the Meeting Hall again, but first solve some other quests. Maybe this has something to do with it? I don't know.
