What happens when the film speed dial gets knocked loose...

Something weird happened to the film speed dial on the X-370 near the end of this roll. Just after I took this picture, I noticed it had popped up and had been spinning freely. I suspect it had shifted to some higher iso than it was originally set for, which is why this pic is so underexposed. Once I unloaded the roll later that evening, it locked back into place properly (I hope!)
