You don't think maybe it was mad at you for trying to sell it?
The film does go around kind of funny, but I am not sure how one would misload it. I might waste a roll just to see if it is possible. What a bummer. Somehow I have managed to avoid this particular problem, but with the 50 or so sheets of 4X5 I shot before I got one evenly developed sheet, I can feel your pain.
