Suggestion: Peace Treaty 'Achievement'

Every crew gets a peace treaty button. When 95% of a kingdom's members (measured in influence) are 'at peace' with one and other, that kingdom gets a home defense bonus + slightly better yield speeds.

That would be fair after having troll achievements for 5 year olds shoved down our troats, it would give some credibility back to the developers, bc truelly some of these so called achievements are really silly.
