Presumed boolean error, e.g. Objective complete = 0 when it should be 1. Sometimes does not recognize completion of objective. This means the game progresses no further and becomes useless. Error encountered at different stages with mine and my friend's game. I.e. Attack the South Forest, all enemies killed, control gained, objective remains to kill all enemies. I've attached some screenshots that show that the area is controlled, but the objective message still shows.
