So the film had been in the camera for only two and a half months? Unless the camera was in the sun or otherwise exposed to a lot of heat for that period then I cannot see that time in camera is the cause.

If two and a half months in a camera results in a problem like this then I think Simon Galley and his company have a real problem with PanF+ and I do not think they do for a moment.

The problem lies elsewhere
