if used with MPModpack (for using in Multiplayer) everyone can build a Wakan. It costs 10 faith.

Very nice, but crashes Civ V on my computer ( back direct to desktop ). Sometimes at the beginn of the game but at every turn after turn 200. My english is too bad to explain more...
If you got a translator:
Très bien mais après quelques temps de jeu arrête Civ V et renvoie directement au bureau. Pendant les premiers tours cela se passe très bien et puis, cela commence à partir du tour 100 ( environ ), d'abord une fois tous les 10 tours et de plus en plus souvent après. A partir du tour 200 ou 250 cela devient un cauchemar. En ce moment je ne peux plus faire 2 tours de suite sans avoir à redémarrer......
J'abandonne avec regrets car le mod était bien pensé.

@skaz88 It is compatible with HJR as normal, although there is no special preference as Yoshitoshi was a baptized Catholic.

Does this also support The Japanese religions extension?

Much obliged

@Mark Takagi thanks for reporting this! There was an issue where the function to prevent other civs from building the Wakan only ran if So was present in the game. I've just published a fix.

Only gripe with the mod is that you can build the Wakan with any Civ. I'm playing as the Japan and the So Clan isn't even in my current game, and the choice to build the Wakan is there.

Just giving you a head's up.
