It is an outstanding game and I'm astounded that the camera/stones glitch is not being discussed here ? having looked into it since glitching 2 days ago I have discovered posts related to this bug on forums from WEEKS ago ! it breaks the game for us affected by it as you cant continue the story without the camera SPOILER ALERT (scripted spotting of enemies )and you cant abandon this particular mission and at least enjoy the free roam which is terrific.
