One example from my experience: I don't know the exact timing, but on a Quick speed multiplayer game at Noble difficulty a spawn of 3 Mistforms basically killed another player around turn 40.
I really can't say how many times or when this occurs to AI in my single player games but I know it does happen often well before turn 100 on Epic Immortal or Deity (though I don't really care if it's "game-ruining" for an AI when it's single player a lot of the time).
