Yeah so, as fatswan (and others) have explained, I have the same problem, the ranger camp has some game breaking bugs. Also, if there's a building right next to the darkness, warriors sometimes ignore the enemies, and if you have enough healers, this can put you in a loop, forcing you to restart. But besides, the game is really fun, and enjoyable, I look forward to updates soon! ^^
(ps. there could be a troop that the player can control, to make them a little more active during the night)
