no this change happen pretty early on, like about the same time as the first big nerf to hausa when it rushing everyone to death.
i cant actually remember what the card did and it was so early on I cant even find any notes on it. the first wiki page on hausa hc cards was in december 2021, which is like several months after the civ came out by that point.
there is only this mention left, but i think it also used to do something else after the first change
