Early in my current game, I took on a quest titled "The Plague". That went well until I was asked to defeat Agonis the Lich. Took my troops to Agonis' lair, found him far too powerful for the time being, and left him alone. The quest icon remained in the left side bar in the game window. Quite some time later, I want to return to the quest, but Agonis' lair is suddenly gone from the map. It used to be fairly near one of my cities, whose area of influence has since expanded quite a bit. When I click on the quest icon, it does not take me anywhere on the map either. Is this a bug or am I doing something wrong?
