Latest autoexec. During stills shooting today the camera froze and lost a pic. Screen went black and red light came on. Had to pull the battery. Right after, problem happened a couple of times and I didn't lose the photo. It would get sometimes show err in the viewfinder or get frozen on the review screen.
Coming home the camera freezes during review around the same pics. I thought it could be exfat or something with the card but I chkdisk and its good. Rolling back to latest "official" stable autoexec and the reproducible review issue is gone. Something is still amiss... no logs were dropped.
