How does ambient anomaly work if I change my mind later IE want the endgame event? Can I toggle it onto standard from storyteller settings and a monolith drops out of the sky or something, or is it locked once the world is generated? I want to focus on odyssey stuff until endgame so I can comically breeze through all the eldritch monsters with sci fi ships, but I don't want to be tied to a monolith tile or encounter anomaly stuff until then
