While playing as usually, excluding grinding through the constant hidden movement bug, I downed a UFO and sent a team. When I got there, I was pleasantly surprised that the location wasn't the farm or industrial location I'd seen before. All was well until I stepped far enough away from the chopper to realize that parts of the map were missing. It wasn't game breaking, but even the UFO was separated from the rest of the map, making it impossible to ever reach it had the AI decided to camp inside the ship. I'm going to attach screen shots of the broken locations and my game save right before landing.
