Give me a call. Kevin and I tested a ton last night. I was unable to recreate the error or the issue. My gut tells me that there wasnít a successful autofocus run in the logs for the system to look back on for a starting point for the offset so it went to zero. Once I manually ran a single image with autofocus. It worked perfectly every time. Not satisfying answer but itís working just fine now after a week of not working.
