So I was playing as Kaffa, it went pretty great, i PU'd Alodia, got some Adal lands, killed the minors around me and after 20 years i PU'd Ethiopia aswel. So I thought things are going great and vassalized Yemen, gave him his cores back and forced his religion. Again I think this is the greatest Kaffa game I played, especially after i integrated Alodia. I was a great power and Ethiopia's liberty desire went down to 13%, Yemen however was fluctuating between 50% and 55%, suddenly the Mamluks started supporting the liberty desire of Yemen, and started a war 1 month later, to my surprise my very happy PU Ethiopia joined THEM in this war, like what is going on here? i was about to go integrate them in 6 months... they were coptic and the same culture group as me, so I just don't understand why they would side with the Mamluks instead of with me against Yemen (who was half coptic by this point) and Egypt. I know liberty desire goes up when your vassals think they can beat you together, but shouldn't the Mamluk's troops only count towards Yemen and not Ethiopia?
