Summary0006934: Using Seeds in World Gen does not always result in Civs behaving the same way (History Seed broken?)
DescriptionWhen generating a world with fixed Seeds, the civilizations will not always behave the same way during the period of history generated. Even with the same history seed.
Steps To ReproduceGenerate a Small Island with Fixed seeds on all four categories over a period of a 1000 years.

Repeat.

One time we will end in the Age of Death, another time in the age of Fabled, and another time in the age of goblins. Also sites have not been build on exactly the same places, as well as roads.

Starting places and geography are identical but over time alternate timelines will appear each time you generate the world with the same seeds.

I used the default small island advanced param set with all four seeds set at 11111 and over four generations I had different (although similar) results. Related to the new world simulation?
