This is a really annoying bug...
I'm playing as the Romani, and whenever I capture a territory, I am unable to build any units there because the barracks have the wrong culture. So I destroyed the barracks the first time this happened, but was unable to build Roman ones! Now my armies are either made up of local militias or they are troops from Italian provinces that already had barracks to begin with, that take a number of turns to tranport to the right region. what's going on here??
