Sorry if this has been answered already, I didn't see it during a quick search.

While loading the film (and I've had this problem on occasion before - just not during vac. w/ limited film and no 120 in sight) all seems to go right, but then the counter doesnt catch and I burn through the entire roll of film. It's set to "0" as it's loaded and as I forward the film it doesn't stop at "1", just moves on and on and on.... Seems I'm doing something wrong. Is this a shutter issue as the film is loaded? How do I reset the counter correctly to get loaded consistently?
