At about level 22 some strange things started to happen. First, the weapon is was using would disappear from sight. I could shoot, but I couldn't be sure what weapon I was using, and the aiming crosshair also was missing. The second thing that started happening was when I was talking to one of the characters in the game, I couldn't hear what they were saying. The sound of their voice was gone. Sometimes if I turned 90 degrees to the side I would get voice. I had to turn on the subtitles so I could understand what was being said. The weapon thing happens very seldom, but the second happens a lot. Has anyone else had this problem?
