What is timing for Global Conflicts Variant in through the ages?
There is ambiguity, but I would do the Global Conflict culture award first, and then follow the usual start of a new age process as defined in the rulebook.


Discard antiquated cards
Remove antiquated leaders from play
Remove antiquated unfinished wonders.
Remove antiquated pacts
Lose 2 yellow tokens


This could be justified by noting the rulebook seems to list all those as something to do at the start of an age, while the culture award occurs at the end of an age.
