Open the game, go back to a save from before you opened the clans, and use the mod menu to max everything. See if the clans appear. I've tested this many times already, as can be seen in older posts with other people having the clan problem, and it works just fine. If it were a bug, it would affect everyone, but it never happened to me no matter what I tried to do to recreate it, so I still assume you guys are doing something wrong, missing the chiminage, or some other **** (like not having enough glory, honor, and wisdom).
