This conversation has been merged. Please reference the main conversation: Lightroom CC: Crops and local adjustments don't copy properly on rotated pics
When I crop one of the images and sync that crop to the other one, the crop *does not match*—be it with auto sync or manual sync. The image that gets synced ends up with a tighter crop for no apparent reason.
This means I have to try to match the two crops manually by fiddling with the crop rectangle (which is a waste of time and can't even be accomplished with perfection because it is nowhere near precise enough).
I remember cropping multiple images like this some time in the past (with previous versions of Lightroom) without issue, so it's a bug that has been introduced at some point.
