Does anyone know why this is?

I play as a Jurchen tribe aiming for Qing, Silk Road and Land of Eastern Jade. Its still early 1460s and Ming got in big trouble with peasant rebellion and people started dog piling so I did too, my only objective for this first war was to release a core from Xi and Zhou to begin the feeding. I could create Xi vassal without problems but I cannot create Zhou from their core province.

Zhou does not exist atm only thing I can think about is maybe core range, but I doubt I could core the Xi province either, they are both in the middle of south China.

My only guess is that the core you took is not of Zhous primary culture (Cantonese). To create a vassal you need both core and culture. Had that problem earlier in my Ottoman campaign, I took an Iraq core but it was a Kurdish one instead of Mashriqi.

That could be it then, Im pretty sure it was not Cantonese
