I think I at least figured out what caused the issue. I started thinking back. I had noticed that the camera fogged up twice last season. Well, the first time it happened, when I pulled the cam it had been pointing at the ground. When I reviewed the pictures, it had been scewed with by a currious bear. I am guessing the bear broke it in a way that let moisture into the cam. That would explain it starting to fog up at that time. I wonder if there is something in it that is shorted out that I could possibly fix....
