I have restarted this mission a few times now with the same result:
I conquered the first two villages Novy Sobor and Stary Sobor, but then nothing else happens. No cutscene or radio communications.
I built a base, bought some tanks and took over the other 2 villages. Mission doesn't end, the objective of "conquer region" seems to be met, then resets. Nothing else happens.
What do I do now? If I end the mission with the console command, does it mess up further choices in the game?
