I just discovered the Norsemen have changed affinity. They used to be an Expansionist culture; they seem to be Militarist culture now. Is that right or is it a recent bug? Was there any other affinity change in the recent updates?

They were announced as Militarist culture and I don't recall them being Expansionist in-game, though, granted, it might have been a thing, because I've always chose them to settle New World, not use affinities.

I am quite sure Norsemen used to be an expansionist culture.

Well, if Norsemen remains a Militarist culture, the Medieval era is now a bit weird:

• Only 1 expansionist culture: Teutons
• 3 Militarist cultures: Aztecs, Mongols and now Norsemen

Before, it was better balanced: 2 Expansionist and 2 Militarist cultures!

Sorry, guys, it seems it is a mistake from me, it is probably a wrong input in my Excel file ?
I was so sure, shame on me! You can discard this comment.
However, although I can understand it is a deliberate decision of the developers to not balance the affinity in each era, my preference would be to have no affinity be represented 3 times in a middle part of the game such as to have a better balanced game…
