Yeah I don't understand how a Protectorate can just break off its protectorate status with you like that. I mean they became your proptectorate for a reason and that reason is because they face being slaves or Death. I mean I would of thought after they become your protectorate they have the same diplomatic stance as you (ie the Senates Alliance with Brutii and Scpii is null and void since they arent my Allies) and if i Ally or declare war with another faction then they have to as well.

Oh well hopefully a CA dev is reading this and will think of implementing this in the expansion
