How were the odds tweaked so the AI no longer declares war on you instead of focusing on closer enemies ?

Not sure if it's 5.1 with it's mirriad of bugs, but i just had Wurzzag and Belegar ignore eachother for 20 turns , declare war on me (Mannfred) even though i never went near their border ( but they were next to each other )....only to be joined by the Jade Dragon guy and Orion, from across the seas.Oh yeah, and there were some beastmen armies around, nope....homing missle on me :D

Meanwhile , in the south, Kairos decided to declare war on me while i was at war with his enemies....and the Slaanesh faction in the south declared war the second i became visible ( but they were ignoring Teclis/ TikTak ,even though they had no armies there, their settlements were free to pillage )


Is there a mod somewhere which makes the AI a bit more logical ? Dwarfs should be at war 24/7 with all greenskin and skaven; Orion with beastmen ; chaos should fight everyone ; and so on and so forth .
