My "ally" keeps vassalizing or annexing the provinces I was about to take. Is there any way to get them back without losing the alliance?
My Milan->Italy run is being helped by my bestie France, but they just diplo-vassalized two OPMs I was about to (Siena and Urbino), and now they're taking Neapolitan territory that I was about to conquer. I already had all the territory marked as strategic interest. Is there any way for me to get these territories from them without sacrificing our alliance?
