Why can't you ignore it now?
After the conspiracy bar thing fills 3 factions make war on you at once and you're not allowed to make peace until you beat them super hard. Before 1.6.3 there was a bug that let you make peace normally so it didn't really matter.Yeah why can't you ignore it? I've ignored it and made a noob kingdom (as soon as rank 4 with 1 fief and not extra parties, full noob style) and nothing weirs or bad has happened yet.
I'm not interested in easy ways to beat the game or anything like that. This is a problem that significantly harms my playthrough and I want it to be solved.Use your companions.
Make them godlike Clan Leaders and give them the best equipment and they will conquer Calradia in under a year for you.
