Hi,
I eliminated Japan in Classical Era in a game. Much later, I dug our an artifact near his former cities which turned out to be from Hojo (no other options). Surprisingly, the artifact was a map from industrial era.I never encountered that before R&F. I was sure that I remembered a lot that of the fights etc that lead to artifacts and knew beforehand where I need to look for ancient or more modern artifacts (although I often confused ancient and classical fights).
