Something that I saw multiple times during the campaign which is a bit strange IMO is the fact that whenever some clan stay too long on the campaign map they stop having legitimate heirs and begin to choose whatever general they get to control the fate clan which doesn't make any sense :O a guy named Baba toshiyama became the leader of the Takeda Clan its true that sometimes they maked some general their heirs but these new leaders name a new general their heir... they dont bother too make any child, which breaks the game IMO. And I have the same problem with EVERY SINGLE CLAN that lives too long. Does anyone know a way to stop this from happening?
P.S murdering their non-legitimate heirs doesn't change anything since they just hire a new general. Killing the clan leader has the effect of making a new clan leader but who does the same, hiring a new heir.
