1 - No enemies found
2 - People removing defenses, letting the territory for zombies to catch again
3 - Attack a territory and being restarted.
Maybe remove this **** will work better, this is the most anoying part of the game.
But if you can’t remove:
1 - Fix the ‘enemies not found’ bug
2 - The faction which has removed defenses can’t be able to catch the territory again
3 - Fix the restart bug
