Had the same issue. I updatet to 1.0.4 while i was playing the campaign (about 6 Hours irl until the update to 1.0.4).
before the Update i've not seen any tendency for a fraction to took over the map, but after the update i waited in a town for about 30-50 min rl (i was cooking and wanted to "grind" money from the workshops) and after i came back to play i saw that my map was fully conquerd by one Fraction.
So my question is: does the update had an impact on my game altough i started the campaign with version 1.0.3 ?
if yes then the changes doesnt relly helped.
if no, well then, less talkin more RAIDING! (again)
PS: i love the game so far, never had played a game so much in the last time. xoxo
