So, a mate and me did a Head 2 Head campaign, me as Satsuma and him as Saga. Using a pre arranged agreement we took over all the map before fighting each other and Realm Divide never triggered.

I guessed this to be because we were both Imperial, and whoever hits RD becomes the Vanguard, meaning the other player will suffer penalties for attacking them (if they are same allegiance)??

So, we finished it (i won ) and started another H2H, this time i am Sendai and he is Choshu, and so far we havnt hit RD even though he has close to 30 regions.

So, is RD disabled in MPC or is our game bugged??
