It's how the follow player works, the only info it has are the actions taken by the player not the actual camera movements. Storing that would be much more costly. 

I voted for, but does this mean the game is pivoting away from including "Civilizations" to including "Empires"? For example, we had Hellenic civilization before, but it was split into nation-states and later Greek "empires". 

Yeah, but in my opinion a Wonder should ideally be a particular structure, which should be the name of the Wonder, instead of a generic "Kurgan" (if regarded as more inspiring, which I can see why). This also would guide better how it should look like.   And should be. For sure it was maintained (which I doubt for kurgans, mainly after a few years). These damaged versions I'd leave for the future for, well, damaged buildings.

This is indeed a better example and a good question/remark. Just adding food for thought, the Gallic Wonder based on the Sanctuary of Corent is not clean and fresh: So maybe it is a general issue in how 0 A.D. portrays the ancient civilizations.
