Quest information is stored in multiple files in the saved game folder, so it is possible that part of the game knows you have already meet the boar, so will not trigger the quest again, while information stores somewhere else was reset saying the opposite, so Boratus does not show up in his cellar.
If you had not moved any of the crystal balls, I'm not sure how they would be removed (maybe they are only placed there once the succubus is dead, but part of the game though that had already been done?). Reloading a save and waiting before going back to the council hall should not have made any difference.
