How to maximise the stability of your 1.1 game

[Bellum]

-kill an AI faction's Leader and Heir in the same battle (unless it's the faction's last settlement)

Sorry if it's obvious, but why does that cause problems?

By the rules of the game *both* the heir & the leader positions need be passed along the family tree. But apparently RTW struggles with passing both along *at the same time*; as if the game tries to assign the Faction Leader position to the Heir (now dead) and then concludes a terribly embarrasing mistake must've been made upon which it decides to comit suicide out of shame...
(It likely can't assign traits to dead people and is likely not programmed to catch this when handing down the crown... <_<)

However at the last settlement the entire faction is wiped out so that's apparently not an issue anymore.
