So, i was playing a Dwarf Campaign, it was really fun, the final chaos tide had come, and some factions were joining forces to help get rid of them, some of their Norscan, Bjornling and Warherd allies ( as well as teaming up on some beastmen). When all of a sudden we defeat the last two Chaos armies.

Everyone seems to all of a sudden become "aggressive" and "unreliable" Allies fighting side by side start jumping into each others lands and razing cities to the ground, my own Diplomatic rating goes from Reliable to Unreliable because my military allies declare war on each other, forcing me to pick a side in 1 turn.

I get that chaos is supposed to be the big evil, but are all Total war games like this? I was really enjoying the dimplomatic stuff going on. Now everyone is at war. Anyway, enough rambling.

TL:DR
Is there a mod that stops all factions from losing their minds when chaos dies?
