So i'm unsure how to unlock the final mission for the chapter. I've cleared all the current tiles and whatnot and it says that I haven't unlocked the final assault. It might be due to a save and loading issue, but I'm unsure about it. I am unsure if this is supposed to be a game feature or it is a possible minor issue the game might have. I'd like to see if it could be fixed if it is an issue.
Other than that, the game is quite fun to play. Thanks.
