Well, it's more of a "work undone" issue - you spend an hour scouting large camp, stealth killing guards, disabling vehicles so they can't chase you or escape their death and then setting fire around the lot using gas cans and molotovs while withdrawing to safety just to discover that once you move round the corner and back everything is restored, not only guards and camp staff, but gone are also effects of explosions and any traces of fire you set 5 minutes earlier. 6 months of demos how they took trip to africa, made realistic environment with weather patterns, directional wind gusts, sunrise and sunset in real time, and this and that, and birds migrate and foliage rots and mushrooms grow. And ****** enemies rebuild camp in under 60 seconds from restoring save.
